I may not be exactly on target here, but many other ballots being contested, not because the intent of the voter is unclear, but because the chain of custody is unclear. Absentee ballots that came in unsealed envelopes, ballots not properly signed, and with a margin this close, both sides are pulling out all the stops to get their opponents votes disqualified.
And while I agree with the Marlin1975 comment of , "So far from what I see, about 25 or so I have looked at, this should not take a level headed person long to count."
Sadly, like Diogenes looking for an honest man, they are hard commodities to find, and instead this will end up in a court of law regardless if the Minnesota Canvassing Board makes a ruling or not regarding disputed ballots.
