Somebody posted somewhere on Twitter that MI, WI and PA did not report their mail in votes up front. That’s apparently what the “found” votes are all about. They were mailed in ballots for Biden held in reserve. Don’t know if that’s accurate but that’s what someone posted.
Yes, Michigan is just now counting absentee ballots. Most liberals in this state that I personally know, I live in a very blue county, voted absentee unfortunately.
