I think McCain knows he’s been neutered so he’s become a crabby old codger pulling his turtle head down into his progressive old body.
Everybody is pretty aware he threw the 2008 election almost on purpose by rushing back to full frontal support of the TARP Bill when Sarah Palin had started pulling their polls beyond Obamajaad.
To me, he’s deemed him irrelevant.
He threw the election when he told America during the campaign, ‘Senator Obama is a good family man not to be afraid of.’
