Blagojevich (or however you spell it) appoints someone to fill the remainder of the seat. I don't think there's a special election involved. So far the rumors are that it'll be Jesse Jackson, Jr., but I don't think that'll happen because it means that there will just be another House seat to fill then.

He's also going to have to fill Rahm's seat too.

These are going to be two pretty important picks for him, being embattled and up for re-election in 2010.
