Sounds nuts, but I think the only way he has a chance is if Palin decides not to run, but endorse Cain. Trump & Huck decide not to run, and Bachmann drops out and endorses Cain.
This leaves Mitt and Newt to possibly split the RINO vote leaving Cain to capture most of the Tea Party vote. In a 3-way race, I think he may have a chance.
If that combination cant win against Obama..then there's not much hope for the country........ It would be a stark contrast as to the direction the country should go...
