from WND:

Joe Biden these days mostly is slow and stumbling in both his walk and his talk. He often braces himself on a podium to speak. And he’s gained a reputation for randomly looking around and wandering across a stage, trying to get off.

So why, during his State of the Union, was he, as supporters claimed, “fiery?” He shouted and spit words out at hyperspeed, sometimes making a verbal slip but moving on without a correction.

Drugs, suspects one expert. Amphetamine. Uppers.
