Counting ballots
Officials in Florida began counting absentee/mail-in ballots on October 12, 2020. As of November 2020, Florida law included the following provision for counting absentee/mail-in ballots:
(2)(a) The county canvassing board may begin the canvassing of vote-by-mail ballots at 7 a.m. on the 22nd day before the election, but not later than noon on the day following the election. In addition, for any county using electronic tabulating equipment, the processing of vote-by-mail ballots through such tabulating equipment may begin at 7 a.m. on the 22nd day before the election. However, notwithstanding any such authorization to begin canvassing or otherwise processing vote-by-mail ballots early, no result shall be released until after the closing of the polls in that county on election day. Any supervisor, deputy supervisor, canvassing board member, election board member, or election employee who releases the results of a canvassing or processing of vote-by-mail ballots prior to the closing of the polls in that county on election day commits a felony of the third degree, punishable as provided in s. 775.082, s. 775.083, or s. 775.084.[2]
