Before I read the article I can say there are two reasons Obama needs Clinton.
Reason #1 Clinton is smart
Reason #2 Obama is stupid
It's really not that complicated!

I can't think of anyone romney would want as they were all stupid.

Hear the fear emitting from The Holler dweller!
It's too complicated for him for sure.
With Bills 66% approval rating talking him and his policies up to those that Romney and the 24/7 nazi hate radio and The FOX Republican Nazi News Channel has been Lying to ALL these months Bill Clinton is sure to get more Democrat Voters to the polls.
The Holler Dweller claims that the country IS center right but when the Democrats turn out in full force like they did in 2008 the right-wing-nut Nazis lose every time because they are far outnumbered by the left.
They have been telling that BIG LIE for a long time that America is center right !
