Miami-Dade Republicans overtake Democrats as voter rolls shift
Miami-Dade Republicans now outnumber Democrats, driven by a sharp shift in Hispanic registration. The county swung from a 2018 Democratic lead to 464,370 GOP voters versus 440,790 Democrats.
Miami-Dade Republicans held 464,370 registrations to Democrats’ 440,790 on May 19, 2025, the first time the GOP had led the county in recorded history. The shift came in Florida’s most populous county, where Hispanic voters have become the largest registration bloc and where the county’s party math no longer looks like it did in the last decade.
The contrast with 2018 was stark. Miami-Dade’s July 2018 voter report listed 585,379 Democrats, 273,177 Republicans, 531,562 voters with no party affiliation and 1,591 voters registered with other parties, out of 1,388,446 eligible voters in the county’s Aug. 28, 2018 pre-election report. A separate May 19, 2025 count showed 449,337 active Republican voters and 414,680 active Democratic voters. By July 31, 2025, more than 100,000 Democratic voters had been purged from Miami-Dade rolls since February, adding another force behind the reversal.
County demographic tables made clear where the numbers were moving. A Jan. 5, 2026 Miami-Dade analysis listed 789,151 Hispanic voters, 221,248 white voters, 171,283 Black voters and 96,882 voters in the “other” category. Republicans led among Hispanics, 341,429 to 176,513 Democrats. Democrats still dominated Black registration, 131,293 to 6,903 Republicans, while white voters leaned Republican, 77,934 to 72,455 Democrats.
A July 1, 2026 county table showed the same pattern continuing, with 794,063 Hispanic voters, including 343,933 Republicans and 176,895 Democrats. Those totals matter for school-board races and county decisions because they change which neighborhoods and communities campaigns have to target first: the county’s growing Hispanic electorate, the still-important Black Democratic base, and the large pool of unaffiliated and other voters, which stood at 460,783 in the 2025 count.
Gov. Ron DeSantis celebrated the GOP gains in Miami-Dade, though Florida Politics noted he incorrectly called the result a plurality. Democrats have been trying to win back Latino voters in southern Florida, a push that underscores how much Miami-Dade now anchors the party fight far beyond one county line.
