Incumbent Republican Brian Mast seeks re-election in Florida’s 21st congressional district under a new map approved by Gov. Ron DeSantis that tilts the state’s House delegation further toward Republicans. The seat carries a Republican-leaning partisan voting index and has delivered consistent GOP victories in recent cycles, supporting the 85.5 percent Republican probability reflected in current trader pricing. Mast faces a low-key Republican primary on August 18, 2026, while multiple Democrats—including James Martin—are competing in their primary amid significantly lower fundraising totals. Forecasters rate the contest Solid Republican, citing the incumbent’s established support and the absence of competitive headwinds ahead of the November 3 general election. No major developments in the past month have altered these structural advantages.
