How are the polls looking for the 2026 Midterm Elections and what are the key races that you must follow?

The battle for control of Congress is entering its final days with Democrats holding a clear advantage in national polling, although the Republican Party still has opportunities to protect its position in the Senate.

With Election Day scheduled for Tuesday, November 3, the latest PBS News/NPR/Marist survey places Democratic congressional candidates eight percentage points ahead of Republicans among likely voters.

The poll, conducted October 19-20, found that 52% would support the Democratic candidate in their district, compared with 44% backing the Republican.

Independent voters favor Democrats by 13 points, while the opposition party also holds an advantage in voter enthusiasm.

However, national polling doesn't necessarily translate directly into congressional seats, particularly in a political system where individual state contests and district boundaries can significantly influence the outcome.

What do the latest 2026 Midterm Election polls show?

The Marist survey found that 71% of Democratic likely voters were very enthusiastic about participating, compared with 61% of Republicans.

President Donald Trump is also an important factor, with 40% of likely voters approving of his performance and 59% disapproving.

Meanwhile, 44% described their congressional ballot as primarily a vote against Trump , compared with 21% who considered it a vote supporting him.

However, Republican strategist Melik Abdul cautioned against assuming the national polling advantage would produce an overwhelming Democratic victory.

"I don't think it will be the blue wave that people are suspecting," Abdul said.

The economy remains central to voters' decisions, with 34% identifying the cost of living as their leading concern and 33% prioritizing preserving democracy.

Which Senate races could decide 2026 Midterms?

The contest for the Senate remains particularly competitive, with several closely watched states potentially determining which party controls the chamber.

In Ohio, Republican Jon Husted faces former Democratic senator Sherrod Brown , while Texas features a contest between Republican Ken Paxton and Democrat James Talarico .

Maine is another major battleground, where Republican senator Susan Collins faces Democratic challenger Janet Mills .

Other important contests include Alaska, Michigan, Iowa, Kansas and North Carolina , where relatively small changes in turnout could prove decisive.

North Carolina's race features former Democratic governor Roy Cooper against Republican Michael Whatley , making it another closely watched contest.

The Senate remains a more difficult challenge for Democrats than the House because they must gain four seats to secure control, assuming no other changes to the chamber's composition.

What could determine control of the House of Representatives?

The House presents a different electoral challenge, with Republicans defending a narrow majority and dozens of competitive districts across the country.

Democratic strategist Joel Payne believes the party's national polling position is encouraging, although he acknowledged that individual contests remain important.

"The House feels fairly settled for Democrats," Payne said.

However, Republicans are concentrating on mobilizing supporters in districts where voter participation could outweigh the national polling trend.

More than 30 million Americans have already voted, according to figures cited by the University of Florida Election Lab, adding another dimension to the final campaign push.

The central question heading into November 3 is whether Democratic enthusiasm translates into sufficient victories across competitive districts and states, or whether Republican turnout allows the party to maintain control of one or both chambers.
