Having lived in Minnesota there are unfortunately some DFL kooks who will take Franken seriously. Most of these are connected with one of several very liberal colleges and universities (the U of MN in St.Paul, MaCalaster College, and Carlton College where ultra liberal Senator Paul Wellstone taught),are social activists, peaceniks or pacifists or just plain kooks. Outstate Minnesota, i.e. outside the Twin Cities metro area, will not support Franken. I doubt even my Bush hating Minnesota mother-in-law would vote for him.
Amanda Carpenter is terrific. She has a book out about Hillary Clinton as well, the Vast Right Wing Conspiracy's Dossier on Hillary Clinton.
Also, I heard Norm Coleman at CPAC last year (or the year before?) and he was great on the UN Oil for Food scandal-- he's one of the few guys to really go after the UN and Kofi Annan on the issue.
