With fewer than 100 days until Election Day in November, Democrats need to flip four Republican-held seats to gain control of the U.S. Senate. Republicans are defending their majority while facing an unpopular incumbent president and economic pressures from the Iran war and tariffs.
NPR political correspondent Mara Liasson described the contest as one of competing forces. Democrats hold advantages in voter enthusiasm and the low approval rating of President Trump, which stands below 40 percent. Republicans counter with stronger fundraising and redistricting gains that reduced competitive House districts.
Key Senate races remain fluid. In Michigan, the Democratic primary on August 4 pits centrist Representative Haley Stevens against progressive Abdul El-Sayed to replace retiring Senator Gary Peters. Maine Democrats replaced Graham Platner with Troy Jackson, who will challenge Republican Senator Susan Collins in a toss-up contest.
North Carolina offers Democrats their strongest pickup opportunity after Republican Senator Thom Tillis retired. Former Governor Roy Cooper leads Republican Michael Whatley in early polls for that open seat.
