Overview
- Voters will choose all 435 members of the House and 35 Senate seats, including two special Senate contests in Florida and Ohio, with outcomes that set congressional majorities for the remainder of the presidential term.
- Republicans currently hold narrow majorities in both chambers — a 53–45 edge in the Senate and a 218–214 edge in the House with one independent siding with Republicans and two vacancies — making only small shifts in a few districts sufficient to flip control.
- National poll tracking cited in the coverage shows a generic-ballot advantage for Democrats of roughly five to 11 points, a margin that could translate into seat gains but does not map directly onto district-by-district outcomes.
- Early voting is already substantial, with reports of millions of ballots cast and a higher share coming from registered Democrats in many states, while voting rules and mail-ballot windows vary by state and will shape final counts and timing.
- State redistricting and new electoral maps have made some districts more favorable to Republicans in places such as Texas and Florida, and control of Congress will affect legislation, presidential appointments, and federal policy through the remainder of the term.
