Well, the Franken campaign is now explicitly claiming that it is in the lead over Coleman, maintaining that his campaign is using bogus challenges to keep their numbers up.
They say that their lead is somewhere in the mid 20 vote range (here and here)
Basically, they took notes of all the challenges, and recorded the precinct staff’s opinion as to the clear intent of the voter.
Additionally, it appears that 133 ballots have gone missing from a solidly Franken precinct.
Even if the missing ballots are a clerical error, and I doubt it, it’s been clear from the start that Coleman is going full Bush 2000 on this.
