Florida's 21st congressional district features incumbent Republican Brian Mast seeking re-election against Democrat James Martin on November 3, 2026. Multiple nonpartisan forecasters rate the seat Solid or Safe Republican, reflecting its Partisan Voter Index and 2024 results where Mast secured 61.8% of the vote. Recent redistricting further strengthened the district's Republican lean. Mast, a multi-term representative and committee chair, maintains a substantial fundraising edge and advanced unopposed in the Republican primary. Martin narrowly won the Democratic primary but trails significantly in established ratings and overall resources. These structural and financial factors underpin trader consensus favoring Mast, though the general election timeline leaves room for late developments to influence outcomes.
