Sorry but I'm sure you'd like to believe that but he hasn't changed his position on his Guest Worker program proposal. He actually reintroduced it last January but it floated like a brick in the Congress back then. So please, don't pretend this is something new he deviously sprung on Conservatives all of a sudden.
Some of us around here have been discussing this and raising public awareness on this for at least that long if not longer. His very own patsy, Texas Jr. Senator John Cornyn, actually introduced it for him to the Senate back in July of the previous year and is still carrying his water for it for him there.
When did I say this?
