Campaigning in Iowa late last year, Mitt Romney said he would veto a proposal granting U.S. citizenship to undocumented immigrants who were brought to the country as children.

While turning his back on the so-called Dream Act won him support from grassroots conservatives in the Midwest, it brought out Hispanic activists in protest against him ahead of the debate on Wednesday.

“I just want a president who is going to be good for my community, for people who have a dream and want an education,” said Carla Uiquidi, one of a dozen or so protesters in the street opposite the Mesa Arts Center toting placards that read “Veto Romney Not the Dream Act.”

Under the Dream Act, which was brought up in the Senate in May, young undocumented immigrants who have lived most of their lives in the United States and graduate from U.S. high schools would be eligible for a conditional six-year “path to citizenship” if they earn a college degree or serve two years in the military.

Romney told caucus voters in Lemars, Iowa, in late December that he would secure the U.S.-Mexico border with a fence and enough Border Patrol agents to guard it.
