That's because they don't know him yet. My father was one of those Baptists - a deacon in a Southern Baptist Church. I have informed him of Rudy's positions on abortion, gun control, illegal immigration & gay marriage. He says he would never vote for him now. He is now informing other fellow Baptists on his email list of what Rudy's positions are.
The more you know about Guiliani, the more you want to find another candidate.
Glad to hear your father isn't a BINO. ;-)
