President Brownback just doesn't flow.
It sounds a whole lot better than President Frist!
It flows just fine for me. Brownback is a Pub I could vote for with a clean conscience.
OTOH, Frist just lost 5 votes from my family no matter what else he says or does. Before this I would not have been happy with him as the nominee, but I could have voted for him if nothing better showed up. But now he has shown that not only is he a poor, ineffective leader, he can't be trusted to dance with him who brung him.
