Romney and Giuliani are going head to head on immigration. Giuiliani made some reasonable statements about his policies as mayor, which including allowing the children of undocumented immigrants to attend schools, get emergency care in hospitals, and not penalizing those who reported crimes. Somehow, it devolved into bickering about whether Romney employed illegal immigrants at his mansion in Massachusetts.

McCain is now talking about immigration, and he sound unbelievably sad about what the other candidates have said. Speaking of his proposals for solving immigration, he says, "We need to sit down as Americans and realize they are God's children as well. "

Tancredo, on the the other hand, is pleased that most of the candidates are adopting some of his anti-immigrant rhetoric. He's impressed that they're "trying to out-Tancredo Tancredo," he said.
