Senate Control Up for Grabs as Midterm Landscape Shifts
With weeks to go, the Senate majority fight has widened, with Democrats targeting Texas and Iowa and Republicans defending Michigan and Maine.
The battle for control of the U.S. Senate, once expected to be a comfortable Republican hold, has turned into a wide-open contest with less than two months to Election Day. A combination of President Donald Trump's slipping approval ratings, particularly on the economy, and voter frustration over costs has created an unexpectedly difficult environment for the GOP.
Democrats, who need a net gain of four seats to take the majority, now see opportunities in states that were previously considered out of reach. Senate Democratic Leader Chuck Schumer has pointed to Iowa and Texas as newly competitive, alongside traditional targets like Alaska, Maine, North Carolina, and Ohio.
However, the path is not uniformly favorable for Democrats. Races they once felt confident about, such as in Michigan and Maine, have become murkier. In Michigan, progressive Abdul El-Sayed's narrow primary win left the party divided, giving Republicans hope that Mike Rogers, who narrowly lost the 2024 race, can prevail this time. In Maine, Democratic nominee Troy Jackson, a last-minute replacement after the original candidate withdrew, is playing catch-up against five-term incumbent Susan Collins, who has a significant spending advantage.
Texas has emerged as a key Democratic target. Nominee James Talarico and allied groups have outspent supporters of Republican Ken Paxton, who faces longstanding legal and ethical questions. Trump-aligned political groups have recently injected $10 million into the race to bolster Paxton, a sign of Republican concern.
The expanded map has driven projected advertising spending on Senate races to $3.4 billion, a sharp increase from earlier estimates. The economic mood is a central issue, with Trump's approval on handling the economy at just 32% in a July poll. Voters express anxiety over tariffs and inflation, concerns that Republican candidates are grappling with directly.
Senate Majority Leader John Thune has acknowledged the competitive environment, saying he is a realist and worries about losing the chamber. Republicans are betting that their underlying structural advantages and a late push to mobilize Trump's base will carry them through, even as they concede the current landscape is difficult.
