Just FYI, Franken is about the surest thing to being a sure loser if he wins the nomination. I don't much about Ciresi, but trial lawyers who throw money at the electorate typically don't do well in general elections.
Much like Oregon, the crowd for the Democratic nomination for this Senate seat is presently too weak to really have a realistic shot at winning. Let's see if someone stronger enters the contest.
Franken will either be an extremely weak candidate or a very skilled and good one: he's never run for office before, so we'll have no idea what to expect. Remember though: Minnesota elected a professional wrestler as governor.
