TAMPA, Fla. –  After a one-day delay, the Republican National Convention has kicked off, and the party’s overtures to women and Latinos – two groups with whom the GOP has lagged in this election cycle – will make up the centerpiece of Tuesday’s programming.

Some Republican Latinos regarded as rising stars in the party will be thrust into the national spotlight over the next few days, part of a comprehensive effort by the GOP to court Hispanic voters, an increasingly important voting bloc in several swing states.

Among the Latino speakers appearing at Tuesday's Republican National Convention session are Rep. Francisco Canseco, R-Texas, Sher Valenzuela, the Republican candidate for lieutenant governor of Delaware, Nevada Gov. Brian Sandoval, and Texas GOP Senate nominee Ted Cruz.

And Luce Vela Fortuno, the first lady of Puerto Rico, will introduce Ann Romney before her highly anticipated address.

All conventions are choreographed to send a very specific message to voters, and are intended to win additional support that the presidential candidate or party might not have been able to count on.

But the stakes are particularly high for the GOP this cycle given Mitt Romney’s deficit with Latino voters, along with a similar disadvantage with women – groups whom the Obama campaign has assiduously courted as it charts a path toward re-election.

“The party has shot itself many times in the foot with the community; it hasn’t done all it could,” said Al Cardenas, the American Conservative Union chairman who’s long pushed for greater efforts to court Latinos. “The good news for Romney is that the party kind of hit bottom, so the arrow has nowhere to point but north.”

Republicans feel they’re putting forward more powerful voices than ever, though, in their bid to win over Hispanics. Florida Sen. Marco Rubio’s speech introducing Romney on Thursday is one of the convention’s most highly anticipated, as are the speeches by Cruz and Sandoval.

“I think the GOP putting our five highest-level elected Latinos as speakers at the convention is really a very good thing,” said Ana Navarro, a Florida-based Republican strategist.

President George W. Bush won 44 percent of the Latino vote in his 2004 re-election bid, and Arizona Sen. John McCain won 31 percent of the Latino vote in 2008. Both were proponents of comprehensive immigration reform.

In the most recent NBC News/Wall Street Journal/Telemundo poll, Romney won the support of just 23 percent of registered Latino voters – an ominous sign, especially since Hispanic voters are wielding growing influence in several swing states.

“If the polls are accurate, and Romney is under 30 percent – in the high 20s with Latinos – it really is very concerning,” said Navarro.

“If the needle doesn't move, put a fork in Romney because he's done.”

Democrats have been dismissive of Republican efforts to court Latinos as mere lip service for Hispanic voters and their concerns.

"You can't just trot out a brown face or a Spanish surname and expect people are going to vote for your party or your candidate," said Democratic Los Angeles Mayor Antonio Villaraigosa at a press conference Tuesday morning.

But arguably just as pressing for Republicans this week is their need to eat into Obama's and Democrats’ advantage among women.

Obama led Romney 51 percent to 41 percent among women in the August NBC News/Wall Street Journal poll, and the GOP brand lags significantly behind the Democratic brand among women voters. Forty-five percent of women in the August poll had a favorable impression of the Democratic Party, while 36 percent had an unfavorable view; women voters had a 36 percent positive view of the GOP, and a 47 percent negative view.

Republicans are hopeful that Tuesday evening’s speeches by Ann Romney and Washington Republican Rep. Cathy McMorris Rodgers will help soften women’s views of the party, especially on the heels of Missouri Republican Senate candidate Todd Akin’s recent comments about rape.

Other prominent GOP women taking the stage tonight are Gov. Nikki Haley, R-S.C., Gov. Mary Fallin, R-Okla., and New Hampshire Sen. Kelly Ayotte (a rumored member of Mitt Romney's vice presidential short list).

“We’re not in territory where we can’t win … you can lose women by 7 to 8 points and win the election,” said Sara Taylor Fagen, a former communications director in the Bush administration. “We’re in territory with Hispanics where, if over the long term we don’t improve, we can’t win.”

The Obama campaign has seized on instances where Republicans seemed to target access to contraception this past year in order to strengthen its advantage among women; it's backed up that message with millions in television advertising.

California Rep. Mary Bono Mack, a Republican who supports abortion rights, said earlier today on MSNBC that she wished the GOP would use “softer” language in its platform when it comes to reproductive rights.

“I think that we would be better served if we loosened that up a bit,” she said.

But Republicans might be better served to stay the course with their emphasis on the economy and health care rather than contraceptive issues.

“Women in this campaign who are going to vote on the basis of social issues have already probably decided for Barack Obama,” she said. 

Updated, 1:30 p.m. - TAMPA, Fla. -- Los Angeles Mayor Antonio Villaraigosa said that Republicans "can't just trot out a brown face" to make inroads with the Latino community, an increasingly important growing bloc.

As the GOP prepares to showcase some of its rising Hispanic stars during the next two days of its national convention, the Democratic mayor dismissed Republican overtures toward Latinos as insincere.

"You can't just trot out a brown face or a Spanish surname and expect people are going to vote for your party or your candidate," Villaraigosa said at a press conference here organized by the Democratic National Committee.

"People are going to vote just like Anglos do, just like African-Americans do, and virtually every demographic group. They vote for people based on what they say, what they've done, and what they're going to do," he later added.

Among the Latinos speaking in Tuesday's Republican National Convention programming are Rep. Francisco Canseco, R-Texas. Sher Valenzuela, the Republican candidate for lieutenant governor of Delaware, Republican Nevada Gov. Brian Sandoval and Texas GOP Senate nominee Ted Cruz.

But, other staunch opponents of illegal immigration -- like Iowa Rep. Steve King, who's speaking as well on Tuesday -- will also be among the featured voices in the day's program.

"I don't think it's going to do much for him, frankly," Villaraigosa said of the GOP's overall message.

The Los Angeles mayor predicted that President Barack Obama would win "close to 70 percent" of the Latino vote in his re-election effort; Romney advisers have set a goal in the upper-30th percentile in targeting Hispanic voters.

Latino voters are of particular importance in swing states like Colorado, Florida and Virginia -- a sign of shifting demographics that Republicans have worried would put them at a long-term political disadvantage unless they were to become more welcoming of Latinos.

Ryan Williams, a spokesman for Romney, said in response to today's Democratic bracketing event: "Today, as we learn that more than a quarter of Democrats believe President Obama does not have a clear plan for creating jobs, his surrogates in Tampa continued to launch false and baseless attacks against Governor Romney.  The facts speak for themselves – with 23 million Americans struggling for work, nearly one in six Americans living in poverty, and median incomes declining, the Obama campaign cannot defend a record of broken promises and failed policies.  Mitt Romney and Paul Ryan have a plan to strengthen the middle class by creating jobs and turning around our economy."
