It's time to ask: Is John McCain losing it? At 77, the irascible Arizona Senator has become the "get off my lawn" cranky-old-man symbol of the GOP's generational problem, but it's gotten worse lately, with his most recent pronouncements on the Bowe Bergdahl-Taliban prisoner swap calling into question his mental competence. Commenting on the prisoner swap, McCain said on CNN's "State of Union" the five released Gitmo detainees are "hardcore military jihadists who are responsible for 9/11″ and "I wouldn't release these men, not these men. They were evaluated and judged as too great a risk to release."

None of these statements are even remotely true: and, what's more, the Senator surely has access to information directly contradicting his assertions. So either he's lying, or he's gone senile.
