Voters weigh Iran war costs as control of Congress hangs in balance

The war with Iran has emerged as a central issue in this year's midterm elections, with voters in major cities across the country weighing the conflict against other economic concerns on their ballots. According to the Associated Press, the election is being viewed as a referendum on President Donald Trump's second term, with many citizens expressing anger over the unpopular war and high prices. As of Monday, more than 57 million people had already cast their votes, surpassing early voting numbers from four years ago in many closely watched states.

Polling data from the AP and NORC indicates that 35 percent of U.S. adults approve of the president's job performance, while only 25 percent approve of his handling of the economy. About seven in ten Americans say the country is heading in the wrong direction, with most blaming the administration for high prices. This sentiment is driving Democratic voters who are focused on the cost of living and the need for oversight of the executive branch. The Associated Press notes that Democrats are cautiously optimistic about their chances, while Republicans are bracing for a potential loss in the House.

In the House race, all 435 seats are up for grabs, with Democrats needing a net gain of three districts to secure a majority. Republicans currently hold 218 seats and can afford to lose no more than two. Ballotpedia identifies 46 battleground districts, with 25 held by Democrats and 21 by Republicans. A significant factor in these races is the number of incumbents who have chosen not to run, with 60 House members retiring or stepping aside. This open competition allows issues like the Iran war to take center stage without the shield of incumbency.

The Senate contest is equally tight, with 35 seats up for election, including two special elections for the remainder of terms held by Marco Rubio and JD Vance. Democrats need a net gain of four seats to take control of the chamber, while Republicans can lose only two. Thirteen Senate races are rated as battlegrounds by various tracking organizations, including Maine, Iowa, Kansas, and Michigan. In Maine, the Associated Press reports that economic strain and tariffs have made the state competitive, with Senator Susan Collins facing a challenge from Troy Jackson. The outcome in these states will determine which party controls the upper chamber for the next two years.

Money is playing a significant role in shaping the outcome, with the 2026 elections expected to be the most expensive in history. Republican committees have outraised and outspent their Democratic counterparts, aided by Trump-affiliated groups and Elon Musk. According to AP analysis of AdImpact data, 88.1 percent of Republican general election TV ad spending went to states and districts that Trump won in 2024. However, at the candidate level, Democrats have managed to outraise their opponents, suggesting a potential ground game advantage in key districts. This financial disparity is a major obstacle for Democrats, who must compete against a well-funded Republican establishment.

Redistricting has also altered the political landscape, with six states using new congressional maps after mid-decade changes. California, Florida, Missouri, North Carolina, Tennessee, and Texas are voting under these new boundaries, along with Ohio. While Republicans hoped to use redistricting to beat the typical midterm pattern of the president's party losing seats, new districts in places like Florida may not vote as originally drawn. This uncertainty adds a layer of complexity to the election, as candidates in these states must navigate unfamiliar electorates while addressing national issues like the Iran war.

Voter sentiment on the ground reflects the broader national mood. James Moore, a 57-year-old librarian in Raleigh, North Carolina, told the Associated Press that he is paying more taxes, more for healthcare, and more for everything. In contrast, Mark Barker of Palm Beach Gardens, Florida, said he has been following Trump the whole time and believes the president is doing an awesome job. These divergent views highlight the polarization that defines this election, with the Iran war serving as a focal point for those critical of the administration's foreign policy.

If Democrats win control of even one chamber of Congress, investigations and possible impeachment proceedings are likely to follow. House Democratic Leader Hakeem Jeffries has outlined a 100-day agenda focused on the cost of living and oversight of the administration. A strong Democratic night would also boost potential 2028 candidates such as Gavin Newsom, JB Pritzker, and Pete Buttigieg, while potentially complicating Vice President JD Vance's path. Republicans, meanwhile, are trying to hold onto power, with RNC Chairman Joe Gruters stating that everything depends on turnout and that they have been planning to turn out their voters.

The administration has also faced legal challenges regarding election administration, with a federal judge temporarily barring the Trump administration from carrying out a plan to prevent noncitizen voting. Critics argue that this move risks disenfranchising eligible voters and infringes on states' authority over elections. The Justice Department's threats to prosecute local election officials have added to Democratic fears of interference and intimidation. These administrative battles are unfolding while voters are casting their ballots in record numbers, eager to see if the Iran war and economic concerns will translate into a change in Congress.

Wall Street is closely watching the results, with Reuters noting that the outcome could add to investor concerns about AI spending and debt ceiling negotiations. The stability of the new congressional leadership will have immediate implications for market confidence, particularly if Democrats move to increase oversight of the administration's fiscal policies. As polls close across the country, from 7 a.m. in some states to 9 p.m. in New York, the fate of the Iran war as a political issue will be decided by the will of the American people.
