"assured an Obama victory" .   Dream on.   The only thing that killed McCain was his deer in the headlights/ headless chicken approach to the financial crisis.

Bringing her on brought the passion McCain sorely needed--though he needed it at the top of the ticket.    Ask yourself where the passion was in the 2008 general election.




As for Sarah:    only real point to make of this is that, as the country song says:   "It Makes No Difference Now" since she is, as I noted ,"Yesterday's Girl" (Hank Snow, I think.
Whether she did coke or slept around is at this point just a meaningless trivia question.

I suspect the book will be a flop.   At this point, who cares?

And for the reason I cited:   Rick Perry has used up all her oxygen. She waited too long.

I read something that put it quite well:

2011:   she strings it out as to whether she will run.   

2012:    she strings it out as to when she endorses Perry.    She will have no other choice.

Now she's just another rich celebrity.   She may have some influence with her would-be supporters in influencing their choice.   But she can never be that choice.   

And she will eventually have to support Perry.   Only question is when.
