McCain’s already on record saying Hillary could be a good president and that she has integrity.
Obama’s a left-wing empty suit who would sink like a rock in the general election, and take some ‘Rats down with him lower on the ticket.
I don’t know that I could tolerate even a chance of Barack winning in the general. I’ll be happy with a Clinton - McCain race only for the fact that I don’t believe the republic will completely collapse under her leadership (should we ever get to that point). Barack, on the other hand, along with his revolting wife would turn this country into a pandering nightmare.
