2026 Midterms: 18 to 18 Governor Split Shattered, Democrats Gain Five Seats

Tennessee voters cast their ballots on Tuesday, November 3, 2026, in a midterms that featured a historic shift in the nation's executive leadership. Davidson County, along with the rest of the state, participated in a general election that included a U.S. Senate race, an open gubernatorial contest, and every U.S. House seat in the state. The state’s governorship was an open seat, as no incumbent was on the ballot, making it one of 19 such races across the country. In the U.S. Senate race, incumbent Republican Bill Hagerty ran for re-election against Democratic and Independent challengers. While specific state-level results for these offices are still being tabulated, the national context of the night provided a dramatic backdrop for local voters in Nashville, Franklin, Hendersonville, Smyrna, Brentwood, and Mount Juliet.

The 2026 gubernatorial elections resulted in a significant partisan realignment. Democrats won 22 of the 36 governorships on the ballot, while Republicans secured 12, with two races remaining uncalled as of 4:17 p.m. ET on November 4. This outcome marked a net gain of five governorships for the Democratic Party, reversing a trend that had seen Republicans hold a majority of governorships nationwide since 2010. Before the election, the national split was 18 to 18, with both parties holding an equal number of governorships among the states with elections on the ballot. Republicans had previously held a majority of all 50 governorships, with 26 seats, compared to 24 for Democrats.

Ballotpedia identified nine gubernatorial races as battlegrounds, including Alaska, Arizona, Georgia, Iowa, Kansas, Michigan, Nevada, Ohio, and Wisconsin. Four of these governorships changed party hands, specifically in Georgia, Iowa, Ohio, and Texas, all of which shifted from Republican to Democratic control. The open seat in Tennessee was part of a larger group of 19 races where no incumbent governor appeared on the general election ballot. This was due to term limits and voluntary retirements, including fifteen term-limited governors and three others who chose not to seek re-election, such as Iowa Governor Kim Reynolds, Minnesota Governor Tim Walz, and Wisconsin Governor Tony Evers.

The election served as a sharp referendum on President Donald Trump’s second term. Voters cited high prices, the war in Iran, and concerns about government corruption as primary drivers for their votes. In the earliest results, Democrats gained control of both chambers of Congress, a development that has significant implications for the balance of power in Washington. The Associated Press noted that more than 59 million people had cast ballots before Tuesday, surpassing early-voter turnout from the 2022 cycle. This high level of participation underscored the electorate’s desire for change, with many voters expressing frustration over the country’s direction and the cost of living.

National results indicated that Democrats won a net gain of 33 seats in the U.S. House of Representatives, securing a majority with 238 seats compared to the Republican 146. In the U.S. Senate, Democrats gained seven seats, taking control of the chamber with 20 wins against the Republican 13, with two races remaining uncalled. The Associated Press highlighted that this sweep was fueled by dissatisfaction with the administration’s handling of the economy and foreign policy. The shift in power means that Democratic leaders, including Hakeem Jeffries in the House and Chuck Schumer in the Senate, will soon have the authority to launch investigations into the Trump administration’s business dealings and policy decisions.

The election results reflected a notable shift among Latino voters across the country, who swung back toward Democrats after supporting Republicans in recent cycles. This demographic trend was evident in states like Texas and Arizona, where Democratic candidates made significant gains. The Associated Press also noted that record-high diesel and gasoline prices played a crucial role in pushing voters toward the Democratic Party. Exit polls showed that voters cited the cost of living as a central issue, with many feeling that the administration had failed to address their financial hardships effectively.

The Associated Press stated that President Trump acknowledged the election losses but suggested that the results would not significantly alter his calculations regarding the war in Iran. He indicated that the U.S. Might continue its military posture, with the potential for further strikes if Tehran did not reach a settlement. This decision comes amid a complex regional situation involving Houthi rebels in the Red Sea and tensions in the Strait of Hormuz. Analysts noted that the election results might make the president less restrained in his foreign policy decisions, as the political damage from the midterms is now behind him.

Locally, the open governor’s race in Tennessee was a key focus for Davidson County voters. The absence of an incumbent allowed for a broader field of candidates from the Democratic, Republican, and Independent parties. Ballotpedia listed several candidates for the state’s U.S. Senate and House seats, including incumbent Republican Bill Hagerty for the Senate. The election also included local ballot measures, such as amendments regarding bail, property taxes, and crime victims’ rights, which were part of the statewide vote. These local and state decisions will shape the political landscape in Davidson County for the next four years, with potential impacts on local governance and state policy.

The Democratic Party is now focusing on corruption as a central theme for its legislative agenda. Leaders in both chambers have vowed to use their new majority to probe the self-enrichment of President Trump and his associates. This effort includes investigating the administration’s handling of the Jeffrey Epstein case, Immigration and Customs Enforcement operations, and the Trump family’s business deals. The Associated Press noted that this investigative push is part of a broader strategy to hold the administration accountable and to prepare for the 2028 presidential election.
