Cripes, I clicked in to here thinking this would be a serious conversation about Meade.
That being said, I can adjust my targeting a bit - McCain is kind of insane I think and also has been a bullshitter for such a long time, that he doesn't know up from down anymore. We can't expect him to pull off complicated feats like "consistency", as he has NEVER been consistent in matters of importance. The only thing he's consistent about is his sense of entitlement.
With Meade, I'd guess it's a clear case of dementia; I give him six months before he starts shitting himself while wandering around the capitol with his video camera, trying to find his way back to his meal ticket.
