I think what it really comes down to is that Joe Biden is desparately trying to retain his title as "Dumbest Man in the US Senate."
He's faced such stiff competition from Schumer and Durbin and Reid this year that he can feel the 'three-peat' title slipping away.
Biden has to be # 2 our guy in Fla. is the dumbest,bill nelson is far dumber and even proud of it.
