McCain has always fought against the republicans. When he won the nomination he realized that he’d have to start attacking his ‘friends’ on the other side of the aisle.
Soon after he determined that it was better to lose with honor than to fight and win the election by calling out the democrats.
Pathetic - really - but then again, not unexpected by our favorite self-centered sr senator from az.
If the dems end up with 59 senators, don’t be surprised if McCain jumps. They’d offer him any chairmanship he’d ask for. And I’m not kidding.
