New election forecasts indicate that Democrats are becoming more competitive in several key U.S. Senate races ahead of the November midterm elections. The nonpartisan Cook Political Report and Decision Desk HQ (DDHQ) both updated their ratings for Senate contests in Texas and Iowa on Thursday, moving them from Republican-leaning to "toss-up" status. Jessica Taylor of the Cook Political Report noted that while these seats were won by Donald Trump by more than 13 points in 2024, polling now shows the races are increasingly competitive.
In Texas, Democratic nominee and state Rep. James Talarico is polling at levels higher than the party's 2018 performance as he faces Republican Texas Attorney General Ken Paxton. In Iowa, Republican Rep. Ashley Hinson is facing a challenge from Democrat Josh Turek, a Paralympic medalist, amid economic concerns in the agriculture sector. Additionally, Democrats saw recent primary results in Alaska where former Rep. Mary Peltola (D) received 48 percent of the vote compared to 43 percent for incumbent Sen. Dan Sullivan (R).
Republicans currently hold a structural advantage in the Senate, and Democrats would need to net four seats to gain a majority. DDHQ currently gives Republicans a 54 percent chance of maintaining control, down from a 20-point advantage last month. Other competitive races include Ohio, where appointed Sen. Jon Husted (R) faces former Sen. Sherrod Brown (D), and Kansas, where Rev. Adam Hamilton (D) is challenging incumbent Sen. Roger Marshall (R). Meanwhile, Republicans are targeting a seat in Michigan held by former Rep. Mike Rogers (R) against Abdul El-Sayed (D).
The scale of the shift is reflected in national polling data provided by DDHQ, which shows Democrats leading the generic congressional ballot with 46 percent support compared to 40 percent for Republicans. This national environment is influenced by President Trump’s approval rating, which the source reports has fallen to 38 percent, a 4-point drop over the last month. For residents in the Midwest, economic factors like the cost of fertilizer and diesel—impacted by tariffs and the Iran war—are becoming central campaign issues that could influence local voting patterns.
A change in Senate control would have knock-on effects for federal policy regarding data centers, energy, and national security. In Michigan and Virginia, candidates are already responding to constituent concerns about utility bills potentially doubling or tripling due to data center expansion. The shift in momentum suggests the election could be a "coin flip," according to DDHQ analyst Geoffrey Skelley. The final composition of the Senate will be decided on Election Day in November 2026, with runoff elections like the one in South Carolina between Sen. Darline Graham (R) and Rep. Ralph Norman (R) occurring as early as next week.
