John McCain spoke to more than 800 people at Sun City Center on Saturday, where he took some heat for his stance on illegal immigration from an audience member who described his Wimauma neighborhood as a suburb of Mexico where no one speaks English and "illegal aliens" have driven up the crime rate.

"You and Ted Kennedy have the worst record on amnesty," said Buddy Gibbs, a retired cattle farmer.

McCain answered that he's committed to securing America's borders first, and then putting a temporary worker program in place. Anyone who violates the terms of the program would be prosecuted, he said. McCain also said he would immediately deport the estimated 2-million illegal immigrants who have committed crimes. "I have never supported amnesty," McCain said. "I never will and never have." 

Gibbs said he planned to vote for Mitt Romney, "the only real conservative running," and came to the McCain event specifically to confront him on immigration.
