In Miami-Dade, Florida, the discrepancy was about 1.6 percent — a difference of 16,617 votes. Ninety-two percent of the precincts had more recorded ballots cast than voters (for a total of 15,854), and the other 8 percent had more voters than ballots cast (763). Since 12 percent of precincts were missing records, we didn’t include those. That’s a discrepancy that can very well swing elections. For example, in 2018, Republican Rick Scott won Florida’s U.S. Senate seat by 10,033 votes.
Cobb County, Georgia, had a massive discrepancy of 34,893 votes, or 8.8 percent. All but one of the precincts had more ballots cast than voters. The gap was more than two and half times the 13,471 votes Republican David Perdue fell short of winning in Georgia’s first round Senate race in November 2020. Sen. Jon Ossoff then won the run-off the following January.
