Here’s a local PA story from the last few hours:
...Lehigh County elections officials found a couple uncounted ballots in a recount of the Nov. 8 presidential election result in six precincts...
...election officials found three absentee ballots and a military ballot that weren’t previously counted...
I’m told that in the State Senate recount in my WI county, they had under 30 absentee ballots where the voter neglected to sign the envelope. The last I heard, the decision was left to the canvassers as to whether or not to count them. Don’t know the decision.
