This article "Why Do the Election’s Defenders Require My Agreement?" explains much of it with links throughout the examples.
https://amgreatness.com/2021/02/23/why-do-the-elections-defenders-require-my-agreement/"The 2020 election came down to a narrower margin than the 2016 contest: fewer than 43,000 rather than 77,000 votes in just three states. In 2016, nothing fishy in Michigan, Pennsylvania, or Wisconsin—the states on which 2016 turned—was detected. Certainly nothing like:
Counting shutdowns in five states, in which one candidate was ahead, only to lose after the counting resumed;
“Found” tranches of ballots going overwhelmingly—sometimes exclusively—to one candidate, the eventual “winner”;
Sworn affidavits alleging the backdating of ballots;
Historically low rejection rates—as in, orders of magnitude lower—of mail-in ballots, suggesting that many obviously invalid ballots were accepted as genuine;
Mail-in and absentee ballots appearing without creases, raising the question of how they got into the envelopes required for their being mailed in;
Thousands upon thousands of ballots all marked for one presidential candidate without a single choice marked for any down-ballot candidate.
The absolute refusal to conduct signature audits—indeed, the discarding of many envelopes which alone make such audits possible—i.e., of the kind of recounts which are performed not merely to get the math right but to evaluate the validity of ballots;
Other statistical and historical anomalies too numerous to mention here.
All of which, and much more, did occur in 2020."
