Tuesday night’s presidential debate will feature a town hall-style format, where the two candidates will answer questions from a selected group of voters on a wide range of issues.

Instead of the two candidates sitting together at a table, or standing behind lecterns, with a moderator directing the discussion, President Barack Obama and Republican nominee Mitt Romney will talk directly to individual voters and attempt to answer their questions and concerns.  

Participants in this format will be selected by the Gallup polling organization, their questions will be submitted to the moderator, CNN’s Candy Crowley, but asked by the individual voters themselves.

RELATED: Our original request for your questions

The two candidates, seen in this composite of file photos, are set to debate on Tuesday night. What would you ask them?

Over the weekend, we asked readers of NBCNews.com to submit the questions they would ask if given the opportunity to participate in the debate and we received over 4,800 responses.  

The questions covered a wide array of topics and concerns. Many were addressed to a single candidate -- pointed questions asking the president for specifics about the recent events in Libya, or queries directed toward Romney and comments he made about "47 percent" of Americans at a private fundraiser.

Other questions were put to both candidates -- on jobs, the economy, foreign policy, and health care.  

But outside of those, readers had questions on all kinds of issues: The debt and deficit, the environment, immigration, gun ownership, reproductive rights, the war on drugs, the tone of the political debate in Washington, religion and, yes, even one posing the now-revoked Pizza Hut challenge to ask the candidates to choose between sausage or pepperoni.

We can’t reprint all the questions in full, but we culled through the submissions to identify the major themes our readers are most interested in.

Here we've highlighted some of the more prominent areas of questioning we received, along with some actual queries, and the general positions of the candidates.

(The names and locations of our NBCNews.com participants are not included because not all the e-mail submissions included them.)

Help for middle-and lower-income Americans and the unemployed
“All I have heard about are the upper class and middle class. What about those of us who make under $100,000 per year? What are their plans for us? All I've heard is by making the rich richer the rest of us will make more, or have more jobs. That doesn't work for me.”

“Why do we hear all about the middle class but nothing about the poor people?”

“I’m seeing some hiring in our area, but mostly part time with no benefits. Businesses would rather hire two or more part-time employees than one full-time employee which would require them to provide benefits. The lack of work hours prevents these people from affording any sort of stability or standard of living. What would you do stimulate full-time hiring rather than the part-time hiring we have now?”

“How do they plan to deal with the rampant age discrimination that is going on for workers in their 40s and 50s who were displaced by the economic downturn of the past four years?”

Where the candidates stand: Last summer Obama proposed a new stimulus program which would use federal funds to prevent up to 280,000 public school teacher layoffs, pay for modernizing 35,000 public schools, and give tax credits to firms which hired long-term unemployed people.

Romney has said his program of tax simplification, increased trade with Latin America, increased energy production, and more efficient job training would create millions of jobs.

Romney has proposed to lower income tax rates, but also to curb or eliminate tax preferences and deductions so that his entire income tax overhaul would be revenue neutral.

He expects that there would be both income growth and federal revenue growth resulting from a more efficient tax system. He said in the first debate with Obama, "I will not reduce the share (of taxes) paid by high-income individuals."

Right now, people in the top 20 percent of the income distribution pay nearly 70 percent of all federal taxes and people in the top 1 percent of the income distribution pay 24 percent of all federal taxes, according to the Tax Policy Center.

Romney also said, "I will not under any circumstances raise taxes on middle-income families. I will lower taxes on middle-income families."

Obama has proposed to raise taxes on people earning more than $200,000 (single filers) and $250,000 (married couples filing jointly). And he has already raised taxes on them in the Affordable Care Act by imposing higher Medicare taxes.

Also, employees with high-value employer-provided health insurance ("Cadillac plans") will find that their plans will be hit with a new tax in 2018 on the value of the coverage exceeding $10,200 for individuals and $27,500 for family coverage, plus a cost growth factor.

Lingering effects of the 2008 financial crisis and financial sector bailout
“My question would be: What caused the financial meltdown in 2008? Unless we know what happened, then how could we possibly prevent it from happening again? This is something that the American people deserve to know.”

“I would ask Mitt Romney, if you had been president in 2009 when the economy was collapsing, what would you have done to prevent another Great Depression, besides letting GM go bankrupt?”

“How was the repaid TARP (Troubled Asset Relief Program) money used and how should it have been used? Did it pay down debt or go into a slush fund?”

Where the candidates stand: As a member of the Senate, Obama voted for the TARP bailout.

Romney supported the 2008 financial sector bailout, saying it “was the right action to be taken,” citing the need “to keep banks from collapsing in a cascade of failures.”

In the final push in the 2012 presidential election, candidates Mitt Romney and Barack Obama make their last appeals to voters.

Romney has supported parts the Dodd-Frank law which Congress enacted and Obama signed into law in response to the financial crisis, but Romney also said in the first debate that the Dodd-Frank law “has some unintended consequences that are harmful to the economy. One is it designates a number of banks as too big to fail, and they're effectively guaranteed by the federal government. This is the biggest kiss that's been given to New York banks I've ever seen.”

Inflation and the cost of living
“To both candidates, what is the average price for a gallon of milk today?”

“With the economy in a recession and the working class spending more for gasoline, groceries, and all other products, what will you do in the first 30 days to help lower prices in order for the prices of other goods to come down and would you put that statement in writing tonight and have it as public record for the American public?”

Where the candidates stand: In the first debate, Romney did raise the issue of inflation contending that the prices of gasoline food, electricity, and medical care have all increased during Obama’s presidency.

Obama has not made inflation an issue, focusing instead on improving public education, developing American energy, closing tax loopholes for companies that are locate production overseas, and “closing our deficit in a responsible, balanced way that allows us to invest in our future.”

Saving and reforming entitlement programs
“If Social Security is in trouble and needs to be saved, why don't they just remove the cap (on taxable earnings) and everyone pays into it no matter how much money they make. This is a tax on the middle class with a cap of $106,000.”

“I am now sixty-four years old and have worked since I was fifteen years old. Both my employers and I have made payments into Social Security and Medicare for all these years. I retired two years ago and an now receiving a reduced benefit because of my early retirement. How can any candidate or party make plans to do away with Social Security and Medicare, when they are not the ones paying for it? If there is going to be a shortage, increase the employee and employer contribution amounts.”

Where the candidates stand: Obama said in the first debate that “Social Security is structurally sound,” but “it's going to have to be tweaked the way it was by Ronald Reagan and Speaker -- Democratic Speaker Tip O'Neill” in 1983. That 1983 bill included a tax increase and a reduction in future retirement benefits.

In a speech in February, Romney rejected the idea of Social Security tax increases but said “we will slowly raise the (Social Security) retirement age. We will slow the growth in benefits for higher-income retirees.”

In his fiscal year 2013 budge proposal, Obama calls for requiring higher-income retirees to pay higher premiums for Medicare doctor's visits and prescription drug coverage. He also calls for higher deductibles for Medicare outpatient care and doctor's office visits, starting in 2017, and for requiring new co-payments for Medicare home health care services starting in 2017.

He also proposed to give the Independent Payment Advisory Board, a group of independent experts, the power to limit the growth of Medicare spending to the rate of national income growth plus 0.5 percent.

On Medicare, Romney proposes no change for current recipients, but starting in 2023, would people on Medicare to choose among private insurance plans and receive a federal subsidy -- scaled to income to help pay for coverage.

He has also said, "We will gradually increase the Medicare eligibility age by one month each year. In the long run, the eligibility ages for both programs (Medicare and Social Security) will be indexed to longevity so that they increase only as fast as life expectancy."

Energy
“Why nobody is talking about the high gas prices?”

“Why isn't all the petroleum product from our domestic drilling and refining kept for domestic consumption? Perhaps a new publicly owned refinery in the northern Plains states could handle the dirty oil from Canada and give us a source of refined product for all our governmental needs. Isn't this a shovel-ready project that would create good long-lasting jobs and put us further down the road of energy independence?”

Where the candidates stand: Romney has made increasing domestic energy production one of his central campaign themes, while Obama has claimed credit for increased domestic production of oil and gas during the past four years.

But the Environmental Protection Agency this year imposed new clean air rules that limit emissions from coal-fired electric power plants.

Obama said in the first debate that he and Romney “both agree that we've got to boost American energy production, and oil and natural gas production are higher than they've been in years. But I also believe that we've got to look at the energy sources of the future, like wind and solar and bio fuels, and make those investments” through federal subsidies for alternative energy firms.

Romney said he’d double the number of permits for domestic oil and gas development. He also said to Obama, “I like coal. I'm going to make sure we can continue to burn clean coal. People in the coal industry feel like it’s getting crushed by your policies.”

A Romney spokesman said in August that he would allow the wind credit to expire, “end the stimulus boondoggles, and create a level playing field on which all sources of energy can compete on their merits.”

And finally – expressing the perhaps quixotic desire of many readers for more compromise and bipartisan problem-solving in the nation’s capital, these questions:

“If you are unsuccessful in winning the election, would you consider taking a position in your opponent's administration with an eye towards helping to foster bipartisanship? If so, what ideas of your opponent would you be most enthusiastic about supporting?”

Updated Fri., June 1, 10:38 a.m. - President Barack Obama finds himself in a political game of "beat the clock," in which each successive economic report increases in electoral importance.

President Obama, along with his supporters and allies, will likely do what they've done for the past 19 months: hail employment growth but say there's much more work to be done.

The Bureau of Labor Statistics issued a report Friday reflecting dismal growth in employment in the month of May, an indicator of the rate at which the economy's recovery from the recession might have slowed.

The economy added only 69,000 jobs in May, well below economists' expectations. As a result, the unemployment rate ticked upward to 8.2 percent from 8.1 percent in April.

The White House stressed what it has for the past 19 months, hailing employment growth but saying there's much more work to be done.

"[O]ur economy is facing serious headwinds, including the crisis in Europe and a spike in gas prices that hit American families’ finances over the past months," said Alan Kreuger, the chairman of the Council of Economic Advisers. He added a note of caution: "It is important not to read too much into any one monthly report, and it is helpful to consider each report in the context of other data that are becoming available."

Presumptive Republican presidential nominee Mitt Romney and his Republican allies, meanwhile, pounced, arguing that the recovery would be more robust if not for the Democratic incumbent.

"The president's re-election slogan may be ‘forward,’ but it seems like we've been moving backward," Romney said. "We can do so much better in America. That's why I'm running for president."

But the administration’s biggest challenge might be on the calendar, not the campaign trail.

Voters’ sense of the nation’s economic trajectory tends to take shape in the summertime, said Alan Abramowitz, a political scientist at Emory University who’s developed predictive models for presidential elections.

“It's more a matter of how people perceive the direction of the economy, and that's going to be influenced by these reports as they come out,” he said, stressing in particular the importance of midsummer numbers on gross domestic product growth in the second quarter.

Right now, the economic numbers for Obama are essentially borderline –- a variable in keeping with the closeness of the campaign between the president and Romney.

“You would think, based on some of the indicators, if Gov. Romney were making a stronger argument, he should have an advantage in a weak economy,” said former Virginia Rep. Tom Perriello, a Democrat who heads the Center for American Progress’s Action Fund.

GDP figures from the first quarter, released on Thursday, were revised downward to show the economy grew at an annualized rate of 1.9 percent from January through March. And the economy added 115,000 jobs in April.

Both numbers are positive but lag behind the political expectations for the strength of the recovery, especially since Obama’s in his fourth year in office.

First Thoughts: Observations on the latest presidential polls

Lynn Vavreck, a political scientist at the University of California, Los Angeles, suggested that while Obama might not have much time to change underlying impressions, that level of growth might be enough.

“I don’t think he’s the underdog here,” she said of the president.

She said it’s hard for a challenger like Romney to “steal” an election just by arguing that growth hasn’t been on pace.

“These guys are not stealing these elections away from the incumbent party by arguing about whether the economy has been good enough, or whether the growth has been enough,” she said.

Voters’ sense of the trajectory of the economy matters, too. Job creation and GDP growth were far better in late 2011 and the beginning of this year than they seem to have been in the past few months, feeding into a sense that the pace of the economic recovery has slowed.

That sense pervaded the May NBC News/Wall Street Journal poll, which showed Americans’ approval of Obama’s overall job performance and handling of the economy had each ticked downward. Not by coincidence, the horse race between Obama and Romney tightened, too.

To make matters worse, the window is closing on Obama’s opportunity to convince voters that things are improving. At some point, the overall perception of the direction of the economy will be “baked in,” and that raises the stakes for the next few months of economic figures.

“It's important, and it may be the most important thing, given that we're heading toward a close election –-  more important than any campaign event or advertisement,” said Abramowitz. “It's probably going to have more impact if it happens soon, rather than at the end.”

Perriello cautioned, though, about a gap between “substance” and politics, noting that Republicans’ push to cut government spending -– a kind of austerity agenda along the lines of what many Europeans have pursued -– might have contributed to a slowdown for which Obama gets blamed.

“It's not often in history you get a chance to see what would have happened under the Republican approach,” he said, referring to downturns in various European economies. “The politics of that are that if you're in the White House, you have to answer for what the unemployment rate is."

There are other looming variables that could shake up the trajectory of the election. A foreign policy episode in Iran, Syria or elsewhere could dethrone the economy as the No. 1 issue.

Or, when it comes to the economy, a deterioration of the financial situation in European economies could have reverberating effects in the U.S., the political outcome of which is mostly uncertain.

That’s not even to mention the millions of dollars that will be spent by Romney, Obama and their respective supporters to spin responsibility for the economic climate.

“There’s this big elephant that’s out there,” Vavreck said. 

Mitt Romney said he expected the nation's unemployment rate to approach 6 percent by the end of his first term, should voters elect him president this fall.

The presumptive Republican presidential nominee said that he couldn't predict where the jobless rate might stand after a first year in office, but asserted it would decrease "quite substantially" depending on the conditions in the U.S. and abroad.

"I can't possibly predict precisely what the unemployment rate would be after one year. I can tell you, after a period of four years, by virtue of the policies we'd put in place, we'd get the unemployment rate down to 6 percent -- perhaps a little lower, depends in part upon the rate of growth [around] the globe, as well as what we're seeing here in the United States," Romney told TIME magazine's Mark Halperin.

Romney said in early May that an unemployment rate "over 4 percent is not cause for celebration."

The former Massachusetts governor said that his election and subsequent installation of policies would contribute to a change in perspective among businesses, and attract more investment as a result.

"We'd get the rate down quite substantially, and frankly, the key is we're going to show such job growth that there will be competition for employees again," he said. "And wages, we'll see the end of this decline."

The Congressional Budget Office, in its baseline projection of the economic and budget outlook, said it expects the unemployment rate to drop to around 6 percent naturally at some point in 2016, coincidentally toward the end of what would be a hypothetical first term for Romney.
