Florida's voter registration window closes at 11:59 p.m. tonight for the November 3 general election, which will determine the state's next governor, Cabinet members, U.S. Senate seat and legislative composition. As of September 30, the state reported 13.65 million active registered voters: 5.67 million Republicans, 4.12 million Democrats and 3.86 million third-party or no-party affiliation voters. Since the August 18 primary, Florida has added 173,000 voters, with Republicans gaining 73,724 new registrations compared to Democrats' 61,682 over the same period. This shift increased the GOP's registration advantage from 1.54 million to 1.55 million, though Democrats briefly held a narrow lead in September sign-ups. Republicans now represent approximately 41.6% of the electorate, Democrats 30.2%, and independents or third-party voters 28.2%. Online registration is available to residents with a current Florida driver's license or state ID through the 11:59 p.m. deadline. Paper forms must be submitted by Monday's close of business or postmarked by then. The Division of Elections will release its final book-closing report on October 16. Key subsequent deadlines include October 22 for vote-by-mail ballot requests and October 24-31 for mandatory early voting, culminating in Election Day on November 3. Meanwhile, U.S. Representative Byron Donalds predicted his November victory with the statement, 'Somebody's going to have a bad night in 29 days, and it's not going to be me.'
