I suspect that Palin will be the first to go under the bus if McCain get himself in trouble.
She will. She's the only thing keeping that ticket afloat, and someone as infantiley narcissistic as McQueeg can't have anyone outshining him.
The only thing sicker than McCain are the people who refuse to see what a tragically flawed figure he is. (Shakespeare couldn't have done better.)
Give me one "realistic" ( not MSM/DBM baloney...) scenario...that this might happen.
