If Al Franken does manage to eke out a nominal win (by a statistically insignificant margin), the turning point will be rejection of a huge number of bullshit challenges from the Coleman campaign in Hennepin County, particularly in Minneapolis itself, where Franken will recover challenged votes at close to a 10 to 1 rate.
I currently show Franken leading, although by a scant 20 votes. That's real votes, not the Star Tribune's simplistic projection. That margin is quick and dirty, and I'm regretting not looking more carefully at factors beyond voter intent. It's just too close to guess.
There's no way this is not going to court.
