Apart from that concern I would be open to looking more closely at Sen. Brownback.
I'm willing to look at all the candidates. There has not been a good track record for candidates out of the senate. I asked the question on FR not too long ago about the last (republican?) president to come from the Senate. I think someone said Coolidge, but I don't really remember. It was long ago.
Lord knows that Dole was a huge mistake and a huge disaster. (Perot was the real mistake.)
