Bush has never shown any other stance towards the open border issue. Do you really expect him to change now?
Yes, simply because DeLay seems to have entered this debate on the side of enforcement and a "temporary" guest worker program. I tend to believe that DeLay represents the position of teh White House. Even the article says that they think Bush probably supports the Ky/Cornyn Bill in private.
IMO Bush is a lost cause on this illegal immigration alien issue as he has already been bought and paid for. He and his OBL LaRaza cadre will have to be be fought in the Congress and in the neighborhoods and streets, to win over the hearts and minds of our fellow American tax paying citizens before it is too late.
