Serial liar, and should have been perjurer Senator Roland Burris (D-IL) has decided not to run for a full term in 2010.

Burris, who told so many lies about how he got his senate seat from impeached governor Rod Blagojevich that his nose enters a room 5 minutes before he does, says he wants to "protect his legacy." One might inquire what "legacy" he's speaking of - perhaps his legacy of lies to members of his own party, including Dick Durbin who vouched for him with Harry Reid and the rest of the Democratic caucus when they were of a mind not to seat anyone appointed by the disgraced governor.

But no. It turns out that no one - not even the Chicago moneybags who have financed his mediocre career for 20 years - are willing to give him any money to shame the state even more than it is usually shamed by corrupt politicians.

Michael Sneed of the Chicago Sun Times got the scoop:

 To wit: Burris, whose decision to vie for Barack Obama's seat landed him in the midst of a federal pay-to-play corruption probe of Gov. Rod Blagojevich, decided to end his 20-year political career at the end of his term -- "because he was primarily concerned about his legacy," a source close to Burris told Sneed. •      •      Translation: "After 20 years in government service, Burris didn't want the last four months in office to be that legacy," the source said.

•      •      The upshot: Sneed is told Burris was planning to announce his decision today -- and initially planned to only issue a press advisory and not field questions from reporters. Stay tuned.
