Rod Blagojevich is going to be indicted and impeached. The indictment is expected at a time of Patrick Fitzgerald's choosing. The impeachment is going to be done by February. They don't need the same burden of proof to impeach as to convict, so it's going to happen. In six weeks Blagojevich won't be the Governor. And he's been told that no appointment he makes to the US Senate would be acceptable. Therefore, it makes perfect sense that he would choose former state Attorney General Roland Burris to replace Barack Obama.
There is no chance that Burris is seated. Senate leaders have already said they wouldn't do so, although there is some question about whether they have that power (I think the Constitution is pretty clear that they do).
Blagojevich is nuts.
...amazingly, he's doing a PRESS CONFERENCE to announce this. Talk about the Alpha Dog of the Week.
