While former Republican presidential nominee John McCain may be a big supporter of Mitt Romney, the Arizona senator isn't a fan when it comes to the GOP frontrunner's policy of "self-deportation" for undocumented immigrants.

During a recent NBC Republican presidential debate in Florida, Romney explained that he would make life for undocumented immigrants so uncomfortable that they would leave the country voluntarily.

"People decide that they can do better by going home because they can’t find work here because they don’t have legal documentation to allow them to work here," the candidate said. "If people can’t get work here, they’re going to self-deport to a place where they can get work."

On Saturday, Univision's Jorge Ramos asked McCain if such a policy was humane.

"No," the senator admitted. "I think there are some people who want to leave this country and return to the country they came from, but obviously it requires a broader solution than that, and we all know that."

"Do you think that Republicans have lost the Hispanic vote for this election?" Ramos wondered "And, therefore, they're about to lose the White House again?"

"Well, I don't know if they're going to lose the White House again," McCain replied. "But we have to present a humane approach to a very difficult issue of illegal immigration into this country."
