Burris may be a Chicago hack politician himself, but I think that he should be seated. He is certainly no worse than current senatorial incumbents, and there is nothing in the Constitution or the law which says that he cannot serve.
Furthermore, why should he be inconvenienced just to enable the Democrats to fain horror at the governor’s alleged misdeeds?
No question he should be seated from a legal standpoint. Absolutely ridiculous if the Democrats do not. It’s not like there is an election in question.
