The last pre-recount margin was Coleman, +215.
Each side has so far challenged just short of a thousand ballots. And then, will the Senate seat or deny seating to Coleman if the recount comes out favorable to him? Will there be an ethics investigation and no seating until after a trial, on the Nasser Kazeminy money?
This might last, court review canvassing board and all, longer than the Georgia runoff, with voting set there, Dec. 2. If it is a quick count and a decisive margin, Minnesota could be determinative of a filibuster proof Senate (presuming Lieberman holds his present course and the Dems do also).
That's a major factor.
Here is the Secretary of State's screen shot, look at the challenged ballot numbers, and compare that to the 215 vote spread - the spread is swamped. As always, click to enlarge and read the numbers, as of 8 pm, Saturday.
