Y-e-s-s-s. Nails it but good.
IMHO, the tipping point was 2008 McCain actually defending his opponent Obama on the campaign trail.
A notorious obnoxious scene was McC demeaning a Republican on broadcast TV b/c she said a discouraging word about Democrat Obama.
All-out for Obama---as if the short lisping incoherent Senator was Democrat campaign manager.
McCain also allowed himself to be hog-tied by parasitic neocons----their presence made his grossly mismanaged campaign an atrocity to most observers.
But not to worry---McC will suck it up and get happy at those Las Vegas prostitute parties he frequents.
