I think I can safely say that I speak for a good number of Freepers when I say that we have overwhelming proof that US Senators make the absolute worst Presidential candidates, and that I will not support another Senator for President no matter which Party he runs with.
DeMint is a movement leader though. I generally agree about Senators as candidates, but the truly principled leaders could be good. I would say the same potentially about Rubio in about 8 years if he continues to prove his leadership on conservative issues.
Who are you hoping is nominated?
Failure to support a good man and candidate only because he is a Senator seems painfully ignorant and irrational to me.
