Does Obama hang out with anyone who isn't corrupt?

It seems that EVERYONE that Obama has associated with in his life is either a scum bag and/or a complete crook.  The lastest is his good buddy Blago.

If there is one thing i new from the time i was a young kid is that bad people hang out with bad people.  It will be impossible to convince me that Obama has somehow remained and innocent "friend" to all these crooks that he surrouned himself with.  There is no humanly possible way that he is as clean as he comes accross.
