To me, that was trolls...people not holding public office. It wasn't actual congresspersons and senators like Rubio (for one) making accusations.
But, you never hear them chastise the bigots, haters and scumbags in their big tent, do you?
Decrepit cretins like McCain lend legitimacy to knuckle-dragging neanderthal righty-retard birthers when they answer questions about whether Obama's a muslim with 'not that I know of'. Puh-leeze.
