The vindicativeness of John McCain, to the very end.
He lost the 2008 race because unlike Palin he did not offer a forceful GOP voice for any forceful GOP position. He ran as “I am not Obama” and as if he just deserved to be elected, because of his carreer, in a similar manner as did GHWBush when he lost to Clinton (which actually may have been an election thrown to Clinton by the petualant and Bush hating H. Ross Perot).
And he had to wrestle with Her advice to fight for Michigan, which he did not do, in fact, they pulled out. She denoted in her book we will go back their.
Had he listened to her and fought for MI, OH, PA, and WI the way Candidate Trump did, we would have possibly said a found farewell to President McCain in 2016 as he retired.
And it is just a hunch as why he was so bitter towards PDJT, besides PDJT's comments about heroism ( which I have heard echo'd on Fox by those willing to discuss what Vet's talk about on the down-low ) and that is PDJT won States and did things he didn't think too get-er-done, and the rest is history.....
Palin McCain were ahead in the polls till the financial crisis hit
Since it was a a GOP president they got hit with the fallout
