When did McStain ever question Obama? He never questioned his eligibility, nor pointed out his associations. Those were off limits, in spite of Palin's desire to put them in front of the public.
Although I don't care much for McStain, I think he was sandbagged by his own campaign staff, who would rather lose than have Palin, the daughter of a backwoods teacher, and pretty much "redneck" to the core, have any share in the government or the credit for the win.
And some of those staff were Dems and/or had worked for Dems and at least one went and worked for Dems after.
Scum.
