In Virginia, all the absentee ballots for each county go to a centralized precinct. They are counted, and reported when counting is complete. Fairfax is like 70%+ democrat, is the largest county by far, and when they dumped their absentee ballots (which were largely from democrats, because republicans wanted to vote in person), that gave Biden a huge bump.
Our numbers were never close to being “more than we had registered”. All of our votes are paper ballots, which go through scanners to be counted. Every paper ballot is sitting around waiting for someone to pay millions of dollars for a recount. Frietas did NOT request a recount, so he clearly believes that the paper ballots exist, and would show the same result as the first count. His was the only close race.
The ‘problem’ is in the counting, regardless of paper or not.
When scanned, a ballot for Trump will add a ballot and a fraction for Biden................
