I don't know about every evangelical, but I certainly thought of George Bush as being "one of us". And I don't remember the party being put off by that.
In fact, I haven't seen the party being put off by Huckabee being "one of us". I see them being put off by his attacks on the President, and his insistance that he's the only real pick for evangelicals, simply BECAUSE he is one.
I'd prefer a strong christian, or at least a man of faith who practices their faith, but I don't pick my candidate simply because they belong to my church, or have the same hair color I do either.
Huckabee’s immigration policy is why I can’t support him. Everyone who infers I am a racist for being against amnesty for illegals is off my list.
