Republicans are heading into the US midterm elections locked in a tight battle to retain control of both chambers of Congress, as Democrats seek to turn voter frustration over the cost of living and the policies of President Donald Trump into electoral gains.
The fight for control of the 100-member Senate is especially competitive. Republicans currently hold 53 seats, compared with 45 for Democrats and two independents who caucus with them, leaving the balance of power within relatively narrow reach.
Of the 35 Senate seats up for election on Tuesday, Democrats need to hold on to their current tally and win four more to secure a majority of 51. If they fall just one short, however, the Senate will be split 50-50 and Republican Vice President J.D. Vance will be the tie-breaking vote, leaving Republicans in control.
Foreign policy has also made its way into several races: the war with Iran and rising diesel prices are squeezing Iowa’s farm economy, fuel prices are an issue in Ohio, and the US position on the Israeli-Palestinian conflict has become a prominent issue in Michigan.
The results of the congressional elections will help determine how much room Trump has to pursue his presidential agenda.
According to the Cook Political Report’s Senate race ratings, seven contests stand out as particularly competitive and could help determine which party controls the Senate.
Michigan: The Economy and Voter Turnout
In Michigan, Democrat Abdul El-Sayed is facing Republican Mike Rogers in a battleground state that has proved difficult for either party to claim as a reliable stronghold.
Opinion polls conducted in October show a close race, with El-Sayed holding a narrow lead in some surveys. The contest is focused largely on the economy, jobs and the future of the auto industry, whose unions — particularly those representing workers at General Motors and Ford — wield considerable electoral influence.
Dante Chinni, director of the American Communities Project in Michigan, told MBN that Trump’s tariffs have hurt the state because of the auto industry’s close ties with Canada. Persistent inflation, he added, has given Democrats an advantage on economic issues.
Chinni said turnout among independent voters and African American voters in Detroit would be decisive, noting that El-Sayed needs to mobilize these constituencies.
Both El-Sayed and Rogers are also seeking to win over Michigan’s Jewish voters, with the US position on the Israeli-Palestinian conflict emerging as a prominent issue in the contest.
David Dulio, a political science professor and director of Oakland University’s Center for Civic Engagement, said El-Sayed had made the issue a central part of his campaign. It has attracted particular attention among Jewish Democratic voters, he said, noting that Michigan has approximately 100,000 Jewish voters who identify with the Democratic Party.
Texas: A Test for the Republican Stronghold
In Texas, Democrats are hoping to make a historic breakthrough with James Talarico, who is challenging Republican Ken Paxton in a state where Republicans have dominated Senate elections for three decades. The last Democrat to win a Senate seat in Texas was Lloyd Bentsen in 1988.
A joint poll by Texas Southern University and YouGov showed Talarico leading with 49 percent of the vote, compared with 47 percent for his opponent.
Paxton’s campaign has raised $19.5 million, while spending on the race has topped $500 million since the primaries, including more than $300 million from Republicans, according to National Public Radio.
John Taylor, a political science professor at the University of Texas, told MBN that immigration policies and declining support for the MAGA movement could prompt Latino voters to punish Republicans at the polls. The outcome, he said, could signal that Texas is gradually becoming a competitive battleground state.
Taylor does not expect Texas to turn fully Democratic this year, but said any Democratic gains would worry Republicans as they look ahead to the 2028 presidential election.
Ohio and Alaska: Fuel Prices and a Legal Fight
In Ohio, Republican Jon Husted is defending his seat against Democrat Sherrod Brown, a former senator. Economic concerns, fuel prices and the expansion of artificial intelligence data centers are giving Democrats an opportunity to reclaim a seat in a state Trump has carried three times.
In Alaska, Democrat Mary Peltola is challenging incumbent Republican Dan Sullivan. The race has caused controversy after the US Justice Department filed a lawsuit seeking to block certification of the election results if Sullivan loses, pending an investigation into allegations that voters may have been deliberately confused by the candidacy of another individual with a similar name, Dan J. Sullivan Jr.
The lawsuit alleges that individuals associated with Peltola’s campaign were behind the candidacy of Sullivan Jr., a registered Republican, in an effort to divert votes from the incumbent Republican senator. Democrats and Sullivan Jr. have denied the allegations.
Iowa, Maine and Kansas: The Economy Versus Party Loyalty
In Iowa, Democrat Josh Turek is challenging Republican Ashley Hinson, the incumbent congresswoman who has Trump’s backing. Tariffs, the war with Iran and rising diesel prices are putting pressure on the state’s agricultural economy, forcing Republicans to defend their record.
In Maine, Republican Sen. Susan Collins faces Democrat Troy Jackson. Collins is counting on her ability to outperform polling expectations, having won re-election in 2020. But former presidential candidate Kamala Harris’s victory in the state in 2024 gives Democrats an opportunity to challenge a Republican incumbent in a state that generally leans Democratic.
In Kansas, Republican Sen. Roger Marshall faces a challenge from Democrat Adam Hamilton, with signs of an unexpectedly close contest emerging amid the economic fallout from the administration’s policies. The state’s strong Republican lean, however, remains a major obstacle for Democrats.
The Parties’ Competing Bets
While Democrats are betting on a backlash against the administration’s performance, the National Republican Senatorial Committee insists that its candidates are well positioned to hold their seats.
Bernadette Breslin, the committee’s national press secretary, said in remarks reported by NPR that “the socialist tilt of Senate Democrats has reached its peak.” She described what she called attempts to deceive voters in Alaska as “criminal acts.”
Voters in Republican-leaning battleground states, she added, are preparing to reject Democratic platforms, singling out Abdul El-Sayed, Troy Jackson and Mary Peltola.
Democratic Sen. Kirsten Gillibrand of New York, who chairs the Democratic Senatorial Campaign Committee, has expressed confidence in her party’s prospects. In remarks, she said: “I feel a tremendous amount of energy. We have so many candidates running in states that are deeply Republican or purple, and they’re making gains. That’s exciting. People want change, and we have an outstanding group of candidates in the field right now.”
As Democrats seek to translate economic and political discontent into votes, Republicans are counting on the strength of their electoral base.
