The numbers you cite only apply if 100% of ballots are returned. Not all absentee ballots are returned. Many of the ballots were automatically sent - a new Florida procedure.
I’m estimating 78% of REP ballots are returned and 70% of DEM ballots are returned. Numbers subject to change as we see the return numbers.
And just for the record, my OH sources say close to 93% of mail in absentees were returned in OH.
