Democrats face a tough map in their quest to flip the Senate this year, but their candidates – both incumbents and challengers – continue to outraise their Republican opponents in several battleground races, new federal filings show.
Both parties are also contending with competitive primaries across the country, with a handful of candidates pulling in big sums over the last three months of 2025.
Senate Republicans are defending a 53-47 majority heading into the midterm elections, which kick off next month, with March 3 primaries in Texas and North Carolina.
