'Maybe he was just high on his drugs again'

Sen. Tom Harkin thinks he knows why Rush Limbaugh disparaged troops who want to end the Iraq occupation as "phony soldiers." [Via ThinkProgress]

HARKIN: Well, I don’t know. Maybe he was just high on his drugs again. I don’t know whether he was or not. If so, he ought to let us know. But that shouldn’t be an excuse.

It's a good an explanation as any I've heard. Then again, maybe he's just crazy.
