It’s not just Democrats who get to contest a U.S. Senator. On the heels of Democratic machinations to keep Rod Blagojevich appointee Roland Burris from taking a Senate seat, Republican Senator John Cornyn of Texas says that he will rebuff any attempt to seat Al Franken if Democrats attempt to seat him before the certification of his victory in Minnesota. The Minnesota State Canvassing Board has been reviewing previously rejected absentee ballots, which process incumbent Norm Coleman’s team has complicated with a state supreme court motion to change the review procedure. Also, the litigious Coleman is threatening to sue.
