Mainstream American voters will not vote for Ron Paul no matter who he is the ticket with either as the presidential candidate or the vice-presidential candidate.
I do like Herman Cain. He has some excellent ideas - but he could never get them through Congress no matter which party is controlling Congress. Cain is an excellent businessman but that is not how Washington runs. He would be out of his element as President or VP.
Goodbye Republicans for another 4 years. The Tea Party has hurt the Republicans fatally.
