"Republican Norm Coleman has conceded to Democrat Al Franken in the Minnesota Senate race, ending one of the longest Senate races in American history and clearing the way for Democrats to hold a 60-seat supermajority in the Senate," Politico reports. "Coleman's concession, given from the front of his St. Paul home, came just a few hours after the Minnesota Supreme Court on Tuesday unanimously ruled Franken the winner of last November's Senate race. In a unanimous 5-0 decision, the court upheld a three-judge panel's April 14 ruling that Franken defeated Coleman in the race by 312 votes out of 2.9 million cast. The 32-page opinion was remarkably decisive, picking apart and rejecting one Coleman legal claim after another."
