Redistricting in May 2026 shifted Florida's 14th District entirely into Hillsborough County, making the electorate more Republican-leaning after Donald Trump carried the new lines by roughly 10-11 points in 2024. This change elevated the seat's competitiveness and drew national attention, with the NRCC targeting it and multiple forecasters rating the general election a toss-up or lean Republican ahead of the August primary. Kathy Castor, the Democratic incumbent since 2007, advanced unopposed and benefits from established local fundraising and name recognition in the Tampa Bay area. Mike Beltran secured the Republican nomination in August and has since adjusted his messaging toward local issues. A July poll showed Castor ahead 46-38, while September ratings adjustments by some outlets have kept the contest fluid heading into November.
