How long will the Minnesota Senate fight go on? The Democratic National Committee is launching radio ads this morning aimed at pressuring Norm Coleman to concede defeat against Al Franken. "Enough is enough," says the narrator, who describes Franken as the victor of the election and the recount. "Minnesota deserves two Senators and voters deserve to have their verdict stand without delay." The ad, airing on local news radio in the Twin Cities, comes after a three-judge panel sided with Franken.
