I gotta go with Jimdandy on this one. "the VP is his flashy handkerchief used to distract for the prestidigitation."
Yes, unfortunately we do have some legislators that we could gently call willfully ignorant, and not comment on their I.Q.
I'm not at all convinced Joe Biden is in this category. It's amazing how much noise and distraction he creates. On purpose? Who knows? Effective? You bet, I'll agree with that pretty easily.
