Whatever we may think of McCain, if it weren’t for him we may not have a potential president in Sarah Palin. So if she endorses him it’s ok with me. She respects him if you read her book.
She also got to know him personally while all of us can only judge what we see from external sources so her view will be different. She may also know whomever he is up against, and thus, have a unique perspective as well there. I think it is more telling Bob's obsession with McCain.. little Bromance going on there I think.
