Santorum is to the right of Trump on illegal immigration and he and Walker are the only two talking about reducing legal immigration.
Problem with Santorum no traction and he can't get his message across to general public. He doesn't resonate.
I’m glad Walker’s views on Amnesty have ‘evolved’, to use his own words - but then so did McCain, until he lost in 2008 - then he ‘de-evolved’. So forgive me if I don’t trust him much more than Rubio.
I don’t think that Trump ever had the history of supporting Bush’s disastrous Amnesty plan the way Walker did.
