US midterms: Five days to go – What the polls say as Trump, Harris campaign

US midterm elections take place halfway through a president’s term. They do not elect the president. Instead, voters choose congressional representatives and senators, helping determine which party controls Congress. That control matters because Congress writes laws, approves spending and can investigate the executive branch.

The article focuses on contests for both chambers. Democrats hope to gain seats in the House and Senate, while Republicans defend their current majorities. Senate races in states such as Texas, Michigan, Ohio and North Carolina are especially important because a few results could determine the national balance of power.

The immediate contest is closely tied to President Trump. A Democratic House majority could block parts of his legislative agenda and investigate his administration. Senate control is harder for Democrats because Republicans hold 53 of the 100 seats, while Democrats hold 47, including two independents who caucus with them.

The latest national polling average shows Democrats with a clear overall advantage. RealClearPolling measures Democratic support at 51.4 percent, compared with 43.2 percent for Republicans. That is an 8.2-point gap, making the national picture look favorable to Democrats with five days remaining.

However, this figure is a broad national measure, not a prediction of every individual race. It combines support across the country, while congressional control depends on separate contests in particular districts and states. Senate races therefore can remain very close even when one party leads nationally.

The Democratic lead has encouraged efforts to mobilize voters, including young people in Michigan. Still, the article reports frustration with both parties and says some Republicans believe conservative support is growing among Gen Z. The national advantage therefore signals momentum, but it does not guarantee Democratic control of Congress.

A national polling lead does not automatically translate into a Senate majority. Senate elections are held state by state, so the outcome depends on which party wins particular races rather than simply on the nationwide vote share. This creates a gap between broad national support and the map of seats available.

Texas illustrates the point. Democrats have not won a Senate election there since 1988, yet Democrat James Talarico leads Republican Ken Paxton 48.5 percent to 46.7 percent in the polling average. Michigan also shows variation: Abdul El-Sayed leads Mike Rogers in one poll by seven points, while RealClearPolling shows a narrower two-point advantage.

Democrats still need several difficult victories to control the Senate. Even winning North Carolina and Ohio while holding current seats would leave them two seats short, according to the article. Alaska and Texas could help, but Republicans are also competing strongly in Michigan.

The article says Democrats need a net gain of three seats in the House of Representatives to take control. They need a net gain of four Senate seats. The Senate target is 51 seats, because Republicans currently hold 53 of the 100 seats and Democrats hold 47, including two independents who caucus with them.

The numbers do not mean the same thing in both chambers. Democrats are seeking enough House victories to reverse the Republican majority, while the Senate map requires wins in several competitive states. Even if Democrats win North Carolina and Ohio and keep their existing seats, they would still be two Senate seats short of 51.

Alaska and Texas could help Democrats close that gap, but those races are not guaranteed. Republicans are also hoping to win Michigan, where polling differs by survey. The Senate contest is therefore more complicated than the House race.

Winning the House would give Democrats an important check on President Trump’s power. They could block parts of his legislative agenda by refusing to advance or approve measures needed to carry it out. This would make it harder for the administration to pass its priorities through Congress.

The House majority would also control congressional investigations. Democrats could investigate the administration and call officials to testify before congressional committees. The article notes that the White House could challenge those demands, so testimony would not necessarily happen without dispute.

This is why the House race matters even if Democrats fail to take the Senate. A House flip alone would change the balance between the executive branch and Congress. It could slow Trump’s plans, increase scrutiny of his administration and turn the remaining congressional term into a period of confrontation over legislation and investigations.

Trump, Barack Obama and JD Vance are campaigning because control of Congress may be decided by a small number of competitive races. National party figures can attract attention, energize supporters and reinforce the importance of voting. Their appearances also signal which states and candidates their parties consider strategically important.

The article reports Trump campaigning in Ohio for Republican Senator Jon Husted. Obama and Vance were also campaigning on Wednesday, in Georgia and North Carolina. Democrats need victories in states such as North Carolina and Ohio to improve their Senate position, while Republicans are fighting to hold their majority.

The visits come during the final five days before the midterms. Campaigning is focused on turning party support into actual votes, especially in close races. The article also describes efforts to reach young voters in Michigan, showing that both parties are seeking groups that could decide narrow outcomes.

The House of Representatives and the Senate are the two chambers of Congress. Together, they debate and approve federal legislation, oversee the executive branch and influence national spending. Their separate memberships and electoral systems create different political pressures, so control of one chamber can matter even without control of both.

The article gives a direct example of this shared power. If Democrats win the House, they could block parts of Trump’s legislative agenda and launch investigations. They could also call administration officials before congressional committees. The Senate, meanwhile, is central to the overall majority because Republicans hold 53 of its 100 seats.

The source does not explain every constitutional power of each chamber. In the current contest, its main point is practical: House and Senate majorities can shape what legislation advances and how closely the administration is scrutinized. This makes both chambers important in the midterms.
