U.S. midterm elections take place halfway through a presidential term to elect members of Congress—specifically, representatives for the House and the Senate. This year, the general midterm elections will be held on Tuesday, November 3, and have the potential to redefine the course of Americanpolitics.

In this context, all 435 seats in the U.S. House of Representatives are up for election, as well as 35 of the 100 Senate seats (which carry six-year terms). Concurrently, 36 of the 50 states will elect governors and officials for other state-level positions, such as judges, for four-year terms.

The partisan composition of Congress significantly influences presidential actions, as the number of seats held by each party serves as a gauge of the current administration's popularity and the reception of its policies. For this same reason, midterm elections help shape the direction of democracy; they allow voters to reconfigure the balance of power and choose lawmakers who are either aligned with or opposed to the president's agenda, thereby influencing the prospects for a potential reelection.

As it stands, the Senate is currently composed of 53 Republican seats and 47 Democratic seats out of the total 100. In the House of Representatives, Republicans currently hold control as the majority party; however, Democrats need to gain only three seats to flip the chamber, given the current tally of 214 Democrats and 219 Republicans.

Against this backdrop, immigration has been a major focus of election campaigns on both sides so far, as it could prove to be a decisive factor in the election results. The issue has become central to political discussions and voter mobilization strategies; since the current administration is openly opposed to existing immigration policies, Republican voters—particularly Donald Trump supporters and MAGA adherents—are likely to cast their ballots for candidates who frequently highlight this agenda and frame immigrant entry as a public safety issue.

Based on the foregoing, we can understand why Republicans are focusing much of their campaign on immigration and the enforcement of anti-immigration laws; the positive reception of Trump’s rhetoric on this topic during his campaign—combined with the widespread dissemination of misinformation and "fake news" within the country's migrant community—contributed to his election victory. Consequently, the segment of the population that opposes immigration and supports Trump’s deportation policies blames immigrants for various negative issues facing the country, using claims that malign this group by directly linking the border to rising crime rates and growing domestic economic problems.

On the other hand, research by the Searchlight Institute suggests that Democrats prioritize justice over the mass persecution pursued by the current administration. The party advocates for an immigration policy that respects human rights and treats the immigrant population with humanity and respect. In this regard, the contest could be decided by undecided voters who are open to supporting either party. Other significant issues involving the Trump administration—such as foreign policy and the economy—also influence public opinion.

In short, the midterm results represent a direct response to and assessment of the country's political situation over the past two years and shape public expectations for future terms, with the issue of immigration playing a crucial role in voter decision-making.
