Romney has said he would veto that legislation, a Senate proposal to allow illegal immigrants brought to the U.S. as children to achieve legal status -- one of several rightward gestures on immigration he made during the Republican primary that now poses a challenge as he attempts to woo Hispanic voters as a general-election candidate.
Thus far, Romney's strategy appears to be to stick to his major overall themes -- education, the economy -- and hope they resonate with all voters, including Hispanics. But advocates, including those in his own party, say he won't get far without addressing immigration head-on at some point.
The evidence was right there at the venue where Romney spoke Wednesday, the U.S. Chamber of Commerce. Marco Rubio, the Florida senator who is one of the Republican Party's brightest hopes and a top contender to be Romney's running mate, spoke a couple of hours after Romney and addressed the issue frontally.
Rubio spoke movingly of the parents and grandparents who'd sacrificed so their children could have better lives. He called the country's immigration system "broken" and lamented the plight of "hundreds of thousands of young people that have grown up among us, who find themselves in an undocumented status through no fault of their own ... and yet, because of partisan politics, we've been unable to figure out a way to accommodate them within the confines of our heritage as a nation of laws, but also our legacy as a nation of immigrants."
"We are but a generation removed from a very different life," Rubio added. "It's not fair for the story of America to end with us."
Romney has yet to take a position on Rubio's proposal for a Republican version of the DREAM Act, which faces long odds in the Senate. He has touted the idea of "self-deportation" for illegals -- immigrants' advocates view this as a euphemism for making life so unpleasant for the undocumented that they are forced to leave -- and called for a fence along the Southern border.
To be sure, immigration is not the only issue of importance to Hispanic voters. In one recent national poll, conducted by charter-school advocates, 73 percent of Latinos called improving the economy an extremely high priority, while 61 percent cited education; just 37 percent put reforming immigration at that level of importance. But the perception that Republicans have singled out Hispanics with their harsh immigration rhetoric remains a major obstacle for the party -- a sign, to many, that the GOP would rather placate its vocal anti-immigrant base than expand its electoral tent.
Now, Hispanic Republicans hope Romney can repair the damage. But to do that, they say, he'll have to confront the elephant in the room. "I have no doubt Hispanics have been alienated during this campaign" by the candidates' immigration rhetoric, New Mexico Governor Susana Martinez, told Newsweek recently. "But now there's an opportunity for Gov. Romney to have a sincere conversation about what we can do and why."
