There will be another open Democratic Senate seat in 2026 midterms

Sen. Tina Smith of Minnesota announced Thursday she won’t seek re-election in 2026, forcing the Democratic Party to defend another open seat in next year’s midterm and making more difficult their goal of regaining the Senate majority.

“I’ve decided not to run for re-election to the Senate in 2026,” Smith said in a social media post. “This job has been the honor of a lifetime. For the rest of my term, I’ll work as hard as I can for Minnesotans and our country. Thank you so much, Minnesota.”

Smith was appointed to the Senate in 2018 to succeed former Sen. Al Franken after his resignation over sexual misconduct allegations. She won a special election later that year to serve out Franken’s term and was re-elected in 2020 to a full six-year term.

Senate Republicans vowed to try and flip Smith’s seat in blue-leaning Minnesota.

“Minnesota is in play, and we play to win. Minnesotans deserve a senator who will fight for lower taxes, economic opportunity and safer communities,” National Republican Senatorial Committee (NRSC) Chair Sen. Tim Scott said in a statement to Fox News. 

But the Senate Democrats’ campaign arm quickly pledged to keep the seat in party hands.

“No Republican has won a Minnesota Senate race in over 20 years, and Democrats will continue to hold this seat in 2026,” Democratic Senatorial Campaign Committee (DSCC) spokesperson David Bergstein emphasized in a statement to Fox News.

Senate Minority Leader Chuck Schumer of New York, the top Democrat in the chamber, praised Smith as “a remarkable senator — smart, compassionate, and tireless in her commitment to Minnesota and the country.”

“While I will deeply miss her leadership and friendship in the Senate, I have no doubt that her legacy of service will continue to inspire. We have a strong bench in Minnesota, and I’m confident that we’ll keep her seat blue,” Schumer predicted.

Smith became the second Democrat in the Senate to announce she would forgo running for re-election in the midterms, following Sen. Gary Peters of Michigan, a key Midwestern battleground state.

SENATE REPUBLICANS JUMP OUT TO FAST START IN THIS KEY CAMPAIGN METRIC

Senate Republicans enjoyed a favorable map in the 2024 cycle as they flipped four seats from blue to red and won a 53-47 majority in the chamber.

The party in power – which is clearly the Republicans right now – traditionally faces political headwinds in the midterm elections. And while an early read of the 2026 map shows the GOP will be forced to play defense in some states, they’ll also go on offense in others.

Besides the open seat in Michigan, the GOP will target first-term Sen. Jon Ossoff in battleground Georgia and longtime Sen. Jeanne Shaheen in swing state New Hampshire.

Now the Democrats will have to pay attention to Minnesota, which the Cook Report, a top nonpartisan political handicapper, this week rated as “Likely Democrat,” as it unveiled its first read on the battle for the Senate majority in the 2026 cycle.

However, Democrats aim to go on offense in blue-leaning Maine, where GOP Sen. Susan Collins is up for re-election, as well as in battleground North Carolina, where Republican Sen. Thom Tillis is also up in 2026.

“Tina has always done the work to improve people’s lives: lowering the price of insulin, improving access to mental health services, passing historic climate legislation, and our party’s champion for reproductive freedom. Minnesotans will miss having her in the Senate,” Walz wrote.

There is speculation Walz, who is eligible to run for re-election in 2026 for a third four-year term as Minnesota governor, may now have an interest in his state’s open Senate seat.

Smith, in a video announcement she posted on social media, noted that Democrats “have a deep bench of political talent in Minnesota. A group of leaders that are more than ready to pick up the work and carry it forward. And I’m excited to make room for them to move forward.”

Lt. Gov Peggy Flanagan moved toward launching a campaign, saying in a social media post, “I love Minnesota, and my intention is to run for United States Senate and continue to serve the people of this state. I’ll make a formal announcement later this month.”

There’s also speculation that Democratic Rep. Ilhan Omar of Minnesota, a member of the so-called Squad, may make a move to run for the Senate.
