Where do the candidates stand on immigration?

I just came across this article on where the presidential candidates stand on immigration. It is a difficult and complicated issue, but maybe one of these candidates will finally do something about immigration.

Based on this article and in a nutshell, Edwards, Obama, Clinton, Giuliani and McCain are for some type of guestworker program (with conditions) or even legalization. Huckabee, Paul and Romney are against legalization.
