Scott Walker, possible presidential candidate, says he has changed his mind on immigration. Let me be clear - I think Walker would make an excellent president, but this just seems like straightforward primary positioning. He's doing what he needs to do if he wants a better chance to win in the primaries. That's what he gets. Is it really possible he's changed his mind? Of course it is, but it would not be my first guess as to why he made those statements.
One additional note, this does a terrific job of changing the conversation from the faux Rudy Giuliani controversy.
