The Democratic National Committee announced tonight that they're airing a radio ad in the Twin Cities media market, calling on Norm Coleman to concede defeat after the three-judge court ruled that Al Franken won the election -- the first major step in real political mobilization by either side after last night's verdict.

The announcer starts off by reading the legal language from the court's opinion, that Franken won the highest number of votes and is entitled to the certificate of election, and then emphasizing that Franken is the winner. "Yet Coleman, and national Republicans who want to thwart the will of the voters, have vowed to file more appeals and hopeless legal challenges that will only result in more delay," she then says.

The ad concludes by asking listeners to call Norm Coleman and tell him that it's time to concede defeat: "Tell Norm Coleman to stop putting his political ambition ahead of what is right for Minnesota."
