Sarah Palin or not, he was not making up 96 electoral votes and 7 points in the final vote. McCain got rolled, all Palin did was distract voters from McCain's previous issues.
I do my best and vote for the best candidates. Often times in Az, they aren't Democrat. Dems tend to send out pretty crappy candidates here as people just don't vote for them. The Senate vote is interesting here. Sinema is a right leaning Democrat. She votes conservative 60% of the time. She could actually win, but it depends who makes it out of the other primary.
