The final day of voting in the 2026 midterm elections arrived on Tuesday against a backdrop of significant uncertainty. The day marked the culmination of a year in which President Donald Trump has actively attempted to influence how states conduct their elections and has expressed skepticism regarding the potential for a Republican loss. The first polling locations opened at 6 a.m. EST in a group of states including Connecticut, Indiana, Kentucky, Louisiana, Maine, Missouri, New Jersey, New York, and Virginia.

Millions of Americans have already participated in the election, with early voting turnout currently on track to surpass levels seen in the last midterm cycle. Despite the president's ongoing rhetoric concerning election integrity, the voting process has proceeded with relatively few reported issues so far. This high level of participation stands in contrast to the administration's efforts to use presidential power to sway the outcome of races that will determine which party controls Congress.

The Trump administration has engaged in a high-profile search for non-citizen voters through its Justice and Homeland Security departments. This effort included a pre-dawn operation in California that resulted in more than two dozen arrests. The Department of Justice was preparing its largest ever monitoring effort for Election Day polling places. This federal move was matched by an even larger deployment of monitors by Democrats and allied groups. Additionally, at the president's request, the administration filed a lawsuit to block the certification of Alaska's results if the Senate race favored Democrats.

Election officials and Democratic groups across the nation had prepared for potential disruptions, including the presence of immigration agents or the seizure of voting machines by federal officers. However, the administration maintained that no armed federal officials would be stationed at the polls. In the days leading up to Tuesday, none of the major scenarios feared by Democrats materialized, and most of the Republican administration's legal maneuvers were blocked by the courts.

A significant legal victory for state election authorities occurred on Monday night when the U.S. Supreme Court rejected the administration's push to force California to set aside thousands of ballots. The court's decision was part of the federal search for non-citizen voters. In a separate ruling also issued on Monday night, a federal judge ordered the Trump administration to stop sending lists of alleged non-citizens to state election officials. These rulings follow another Supreme Court defeat for the president less than two months ago, where the court rejected his attempt to limit mail balloting through changes at the Postal Service.

The administration's executive orders during this second term have sought to federalize certain aspects of elections, despite the Constitution generally granting that authority to the states and sometimes Congress. The administration's record of arrests and charges has highlighted a trend shown by prior research and state investigations: instances of non-citizens casting ballots are extremely rare. Election law experts noted that while the Trump administration's lawsuits go beyond historic norms, the legal arguments were unlikely to convince the courts.

Weather conditions also played a role in the day's proceedings. Heavy rains and flash flooding in the Southwest were expected to impede voters in parts of Colorado, Arizona, Utah, and New Mexico. Election administrators in the Navajo Nation announced changes to several polling locations. In Utah's rural San Juan County, voters were permitted to cast electronic ballots on Tuesday due to access issues.

Voting rights advocates and election administrators advised those with late absentee ballots to use drop boxes or deliver them in person rather than mailing them. This guidance came after concerns that recent changes in U.S. Postal Service operations could cause postmarking delays. In this year's primaries in California, Oregon, and Washington, late-arriving or late-postmarked ballots disenfranchised tens of thousands of voters who typically receive ballots by mail.

The period leading up to Election Day was marked by a flurry of legal filings among voting rights groups, Democrats, and the Justice Department. These disputes centered on alleged non-citizen voters, federal election monitors, and the intimidation of election officials. The legal battles are expected to extend past Election Day into the ballot counting and certification processes. President Trump has also continued to offer qualified answers regarding the legitimacy of the results, stating to a reporter a week prior, “I will if they are honest.”
