In this photo taken Friday, Jan. 20, 2012 Ana Rodriguez gestures as she talks about the reasons she will not vote for Mitt Romney in North Bay Village, Fla. Ana Rodriguez, a Miami-based graphic designer who received political asylum and will become a U.S. citizen this year, Romney’s comments are precisely what motivated her to vote _ against him. “Because of what I went through,” Rodriguez said, “I want more people (elected) who are interested in supporting immigrants and want a more equal and fair system of immigration.”

MIAMI — Mitt Romney's promise to veto a measure that would create a path to citizenship for some illegal immigrants threatens to turn off some Hispanic voters. Their support could be critical in a general election match-up against President Barack Obama.

The issue is gaining prominence as the GOP front-runner heads toward the Florida primary, even though most of the state's Hispanics are Puerto Rican or Cuban-American and, thus, aren't affected by U.S. immigration law, nor view it as a priority.

Still, Florida is a state where 13 percent of registered voters are Hispanic, where the nation's largest Spanish-language TV networks are based, and where the nation's third-largest number of illegal immigrants live — intensifying the focus on Romney's position.
