Norm Coleman has made it official: He is filing a lawsuit to challenge the election result in Minnesota, which he does not believe to be a valid count -- and he is making clear that for the sake democracy, Al Franken should not be seated in the Senate.Coleman went through the list of things his campaign says went wrong: For example, that absentee ballots for Al Franken were counted twice, and that there were no uniform standards in reviewing rejected absentee ballots."Until these issues are settled," Coleman said, "any attempt to seat a Senator who is not properly certified violates Senate precedent, and usurps the will of the people of Minnesota."A reporter asked Coleman about the calls from Harry Reid for him to concede -- and was met by booing from the crowd of Coleman supporters. "This race will be determined by Minnesota voters, not Harry Reid," Coleman said with a smile, and to the applause of his backers.Late Update: So how long will this take? Lead Coleman attorney Fritz Knaak told reporters, "I would not be surprised if this went a month and a half, two months out." On the bright side, Knaak said that Coleman would like for it go as quickly as possible.Also from Knaak: "Technically, we could actually redo the entire recount. I'll let you know right now that's not in the plans."Late Late Update: Here's the Coleman video:
