Dominion is the vendor in Antrim Co, MI where an unexplained voting machine error gave the historically red county to Biden. After recount, Trump ahead by 2500. Dominion is used in most MI counties, incl Wayne.

Dominion has the contract for the ENTIRE STATE of GA, where the vendor “uploaded something [Mon] night, which is not normal, and it caused a glitch,” in two counties on Election Day. https://www.politico.com/news/2020/11/04/georgia-election-machine-glitch-434065
In a now-unavailable story at AJC (thanks wayback machine) there were major issues during the testing of Dominion systems in GA back in Nov 2019. https://web.archive.org/web/20200616111812/https://www.ajc.com/news/state--regional-govt--politics/problem-with-new-election-equipment-delays-voting-georgia-counties/vxltEshk0grck0uJiWA5RM/
There were also major problems in GA during their June primary, which was covered by the NY Times. https://www.nytimes.com/2020/06/11/us/politics/georgia-voting-machines.html
Dominion also just rolled out in... Maricopa Co, AZ, where there have been contentions that ballots cast by voters using Sharpies were being rejected by the machines. Dominion contests that assertion, but it happened in... wait for it.. PA last year. https://www.witf.org/2019/11/05/few-reports-of-problems-as-pa-counties-roll-out-new-voting-technology/
As happened in GA this year, in 2019 some PA voters "threw away ballots after excessive wait times," and the PA GOP filed suit after it was discovered 420 ballots were stuffed into a Dominion-provided suitcase and not counted. https://www.fox43.com/article/news/pa-gop-files-request-for-injunctive-relief-regarding-voting-and-ballot-concerns-in-york-county/521-9c41ed46-2139-4357-8ee3-224ea20381ac
Considering that many of the counties in states where the vote is too close to call use Dominion machines, it would be a good idea to go back and verify all of the precinct totals. With observation from both parties and the press.
