Republican Sydney Gruters won Florida's 16th congressional district on November 3, 2026, by a 4.2-point margin (51.2% to 47.0%) over Democrat Kelly Kirschner, placing the outcome firmly in the 3-6% Republican margin range. The open seat, vacated by retiring incumbent Vern Buchanan, featured a redrawn district with a Republican lean evident in recent presidential voting patterns. Gruters secured stronger fundraising and primary support, while final vote counts across Manatee, Sarasota, and Pinellas counties aligned closely with pre-election polling averages around R+4. Certification and any remaining provisional ballots represent the primary remaining variables that could shift the exact margin within that narrow band.
