When Barack Obama captured the Democratic nomination early this summer, many Democratic insiders feared he would not be able to win over Hispanic voters, who overwhelmingly favored his opponent, Hillary Rodham Clinton, in the primaries. Less than two weeks out from Election Day, however, Obama is posting a solid lead over Republican John McCain among this voting bloc.

Despite what many saw as McCain's potential appeal with Latinos, the Arizona senator is garnering less than 30 percent of the Hispanic vote, according to Gallup, far fewer than the 44 percent President Bush captured in 2004. And this could pose a significant problem for McCain in several battleground states.

Obama, meanwhile, is using his cash advantage to reach out to Hispanic voters in many key states with a new radio and TV ad. "Oportunidad" (subscription), a TV spot running in Colorado, Florida, Nevada and New Mexico, presents Obama's plan to give a $4,000 college tuition credit to students who participate in community service activities. It also claims that Obama will offer "scholarships to recruit more teachers to make sure our children are prepared."

An aggressive radio spot, "Ataques" (subscription), or "Attack," accuses McCain and the Republicans of telling "terrible lies." Discussing the hardships his friends and neighbors are facing, one speaker tells another: "Enough with the attacks. We are in an economic crisis, and I want to know what the candidates will do for us." The two then praise Obama's economic policies, with the woman touting his tax plan as the man adds: "What matters to me is that Obama has a plan to give health insurance to all. My neighbor will be saved!"

The 60-second spot is running in Colorado, Central Florida, Indiana, Nevada, New Mexico, North Carolina, Ohio, Pennsylvania, Virginia and Wisconsin, with a slightly different version running in South Florida.

Colorado Sen. Ken Salazar also vouches for Obama in a bilingual radio ad (subscription) that encourages listeners to take advantage of the state's early voting system. Salazar talks about his working-class background and says that Colorado residents share a devotion to family. "You can do something for your family right now: Vote. You don’t have to wait until Election Day," he tells the audience. "With Barack Obama and the Democrats, real change is within our grasp," Salazar declares, hitting on some of Obama's talking points on health care and the economy. "We can’t afford more of the same," he concludes.
