A few weeks ago, Daniela Pelaez visited Washington. A valedictorian at North Miami Senior High, the 18-year-old had just learned she no longer faced deportation, thanks in part to congressional intervention in her immigration case.

She visited the nation’s capital the same week a Fox News Latino poll found Hispanic voters favor President Barack Obama six-to-one over any of the Republican presidential hopefuls. Suddenly, there was new life in the DREAM Act, an immigration bill that offers a path toward citizenship for young people like Daniela who came to the U.S. illegally with their parents.

Enter Florida Sen. Marco Rubio, who has cautioned his party on its stance on immigration, even as he’s considered one of the few Republicans who, with the No. 2 spot on the presidential ticket, could help draw Hispanics to the GOP.
