Well now, let me see. Oh, I know! He could endorse the only conservative who is in the top tier, Herman Cain. I think those two would hit it off great.
He could, if Herman Cain ever gets around to explaining what he did, or what his position on illegals was when he was the head of the National Restauranteurs Association........Which, he has yet to do.....The "N.R.A." is a very very big supporter of the open borders/we need illegals group (Tancredo has battled them in the past).
I honestly have no idea, if, while Cain was there, that was their view, of what impact he had regarding illegals, and Cain, to date, has never really disclosed it, or talked about it. That organization by the way, is pretty hostile to arizona style immigration laws (they claim it'll destroy restaurants across the country), Cain himself hasn't said anything about it, I guess Tancredo is just waiting for him to get around to it.
