Early voting is underway ahead of the November 3, 2026, US midterm elections, when voters will elect all 435 members of the House of Representatives, 33-34 senators, and governors in 36 states. Control of both chambers of Congress is at stake, with Republicans holding narrow majorities in the House (218-214) and Senate (53-47).
More than 100 million ballots are expected to be cast, and political ad spending has reached a record $11.6 billion, according to AdImpact. Elon Musk has contributed $442 million to support Republican candidates, per campaign finance records.
Senate races in Texas, Ohio, and Michigan are among the most expensive, while House control hinges on a net gain of four seats for Democrats. Ten Senate races, including those in Maine, Ohio, North Carolina, Iowa, and Georgia, are considered competitive. Governorships in 36 states and 145 statewide ballot measures are also on the ballot.
Turnout and economic concerns dominate the campaign
Voters are weighing economic pressures, including rising costs of goods and gasoline, as a central issue. Political analysts note that midterms often serve as a referendum on the sitting president’s performance, with President Donald Trump’s approval ratings cited as a factor in Republican prospects. Some polls suggest inflation and the ongoing conflict with Iran are influencing voter sentiment.
Record ad spending and AI-generated content raise transparency questions
This election cycle has seen unprecedented political ad spending, with experts calling it a record-breaking year. Wesleyan University professor Erika Franklin Fowler, who studies political ads, noted that $11 billion has been spent, though research suggests ads have limited impact on shifting voter opinions. A new concern is the use of AI-generated content in campaign ads, including computer-generated scenes of candidates making statements they never made. Fowler highlighted that federal regulations on AI in political advertising are currently nonexistent, raising questions about transparency and voter awareness.
Control of Congress remains uncertain
Republicans are defending slim majorities in both chambers, but historical trends suggest the party in power often loses seats during midterms. Democrats need a net gain of four House seats and four Senate seats to secure majorities. Forecasts from Fox News Power Rankings rate Senate control as a toss-up, with both parties favored in key races. In the House, generic ballot polling has shown Democrats leading by 11 points, though analysts caution that Senate outcomes may differ due to state-specific dynamics.
Key races and ballot measures
Several races are drawing national attention:
- Kansas Senate: Moved from Lean Republican to Toss-up, with Republican Sen. Roger Marshall facing a competitive challenge from Democrat Adam Hamilton.
- Nebraska Senate: Shifted from Likely Republican to Lean Republican, with independent Dan Osborn considered a potential upset contender.
- Governorships: Races in competitive states like Pennsylvania, Michigan, and Wisconsin could shift partisan control of state executive offices.
Additionally, 145 statewide ballot measures cover topics ranging from abortion rights to election laws, with outcomes that could have national implications.
Historical context and voter engagement
Midterm elections typically draw lower turnout than presidential contests, with 155 million votes cast in 2024 compared to projected midterm turnout of over 100 million. Early voting has been robust, with millions of ballots already cast ahead of Election Day. Political analysts suggest that economic dissatisfaction may drive higher-than-usual engagement, though the impact on final outcomes remains uncertain.
