Well he has said in debates it was a mistake. The the people do not trust Washington on this and he would now secure the border first. Problem for McCain is, Can we believe him?
Yes, even if McCain changes his position, do we believe him? Anyway, McCain's words about illegal immigration at CPAC were good but did they go far enough?
McCain does mention the important idea, that our actions shouldn't encourage new waves of illegal immigration. But he doesn't mention and connect his former bill's visa amnesty as something that would encourage additional waves of illegals.
McCain should make that clear.
McCain has time while Hillary and Obahma slug it out. He should author a strong Border Security bill and offer it up in the Senate. Put his actions where his mouth is.
