It may be one of the most audacious political moves of the year: Scandal-ridden Illinois Gov. Rod Blagojevich defied his party today and appointed former Illinois Attorney General Roland Burris to replace President-elect Barack Obama in the U.S. Senate. The announcement stunned Senate Democrats, who released a statement saying they will not seat anyone appointed by Blagojevich.

It is truly regrettable that despite warning from all 50 Democratic senators and public officials throughout Illinois, Gov. Blagojevich would take the imprudent step of appointing someone to the United States Senate who would serve under a shadow and be plagued by questions of impropriety. We say this without prejudice toward Roland Burris’s ability, and we respect his years of public service. But this is not about Mr. Burris; it is about the integrity of a governor accused of attempting to sell this United States Senate seat. Under these circumstances, anyone appointed by Gov. Blagojevich cannot be an effective representative of the people of Illinois and, as we have said, will not be seated by the Democratic Caucus.
