This son of a used-car salesman has always been stupid, graduating only 506 out in a class of 688 even with the tough major of history/political science degrees.
In law school he was even worse, receiving an F after plagiarizing several papers and graduating 76th in a class of 85.
Obama chose him particularly because of his ineptness as Joe would be one of the few people the President would look good in comparison.
His mouthing and blunders while in the Senate are legendary.
The only bright thing he did was to marry a rich girl.
