Major US Senate Turnover Coming In 120th Congress (2027-2029)

The nation will witness a major US Senate turnover in the upcoming 120th Congress (2027-2029).

This would be due to retirements, primary defeats, potential election defeats, and 4 Senators running for Governor.

For now, the following is certain:

The following 11 US Senators are retiring:

Republican Tommy Tuberville of Alabama, running for Governor
Democrat Dick Durbin of Illinois
Republican Joni Ernst of Iowa
Republican Mitch McConnell of Kentucky
Democrat Gary Peters of Michigan
Democrat Tina Smith of Minnesota
Republican Steve Daines of Montana
Democrat Jeanne Shaheen of New Hampshire
Republican Thom Tillis of North Carolina
Republican Alan Armstrong of Oklahoma, appointed temprarily to replace Markwayne Mullin
Republican Cynthia Lummis of Wyoming

The following two US Senators were defeated in primaries:

Republican Bill Cassidy of Louisiana
Republican John Cornyn of Texas

The following seven US Senators are endangered for reelection:

Republican Dan Sullivan of Alaska, challenged by Mary Peltola
Republican Ashley Moody of Florida, challenged by Alex Vindman
Democrat Jon Ossoff of Georgia, challenged by Republican nominee
Republican Susan Collins of Maine, challenged by Graham Platner
Democrat Ed Markey of Massachusetts, challenged by Seth Moulton in primary
Republican Pete Ricketts of Nebraska, challenged by Independent Dan Osborn
Republican Jon Husted of Ohio, challenged by former Senator Sherrod Brown

Likely gains for Democrats seem possible or likely in

Alaska, North Carolina (open seat), Maine, Ohio, and with outside chances in Texas (open seat), Iowa (open seat), Montana (open seat), and Florida.

But Republicans have possibilities in Georgia, Michigan (open seat), and New Hampshire (open seat).

Also, the following US Senators are running for Governors of their states, and if elected, would resign from the Senate, and a replacement would be appointed or elected:

Democrat Michael Bennet of Colorado
Democrat Amy Klobuchar of Minnesota
Republican Marsha Blackburn of Tennessee

IF all of the above were to occur, the maximum number of new US Senators, either by election or appointment for replacements, could reach the mid 20s in number.

Imagining about 20 new Senators as a minimum, is very likely to occur!

Two “Independent” Senate Candidates In Nebraska And Montana Give Hope To Democrats!

Presently, there are two Independents in the US Senate–Bernie Sanders of Vermont, and Angus King of Maine, who both join the Democratic caucus.

In the upcoming Midterm Congressional Elections of 2026, two strongly Republican states have Independents running who give hope to Democrats that if they were able to be elected, they would clearly join the Democratic caucus, while reserving their independence as Sanders and King have done for many years.

These are Dan Osborn, age 51, in Nebraska, and Seth Bodnar, age 47, in Montana, and if either were to win the Senate seats in their states, it would insure that Democrats would control the Senate majority with their help and support on most issues.

This, along with the many potential Democratic Senate candidates who are in their 30s, 40s, and early 50s, would make the US Senate vastly younger in membership for the near future.

Osborn is a US Navy veteran, industrial mechanic, former labor union leader, who challenged incumbent Republican Senator Deb Fischer in 2024, losing by only 7 points, in a race no one thought would be anywhere near that close.

Osborn is now challenging Senator Pete Ricketts, former Governor, who is finishing out the term of former Senator Ben Sasse, who resigned in 2023. Osborn is running as a “rugged guy”, portrayed in similar terms as Graham Platner, who is running for the Maine Senate seat race as a Democrat against Maine Governor Janet Mills, for the opportunity to challenge Republican Senator Susan Collins.

Osborn is running on a populist platform, promoting small businesses, family farmers, and workers, and the Democrats, who have not run candidates in recent times in Nebraska, decided they would support him informally, and not have a Democrat in the race. Early indications show a nip and tuck race in polls, so Osborn just might win as an Independent, and bring relative youth to the Senate.

In Montana, Seth Bodnar, age 47, former President of the University of Montana, is running as an Independent, with no strong Democratic opponent for what will be an open seat, as Republican Senator Steve Daines decided not to run for reelection, and endorsed former US Attorney Kurt Alme minutes before the primary deadline.

Bodnar is a US Military Academy graduate who served in Iraq, and was a Rhodes Scholar at Oxford University in the United Kingdom. He was encouraged to run as an Independent by former Democratic Senator Jon Tester.
So there is a reasonable chance that Bodner could win the Senate race as an Independent, but with leanings toward the Democratic Party agenda, and would likely join the Democratic caucus in the Senate as an Independent.

Four Potential Senate Gains For Democrats In 2026

Beyond Alaska and Maine, and long odds Iowa, there are four other Republican Senate seats that are in play in the Midterm Elections of 2026.

Nebraska has Republican Pete Ricketts, former two term Governor, and part owner of the Chicago Cubs baseball team, running for a full term, after succeeding the retired Senator Ben Sasse in 2023. Ricketts has a conservative record, and will NOT have a Democratic opponent, but interestingly, he will have an Independent opponent, Dan Osborn, who polled well against Senator Deb Fischer in 2024, losing by only 6 points, amazing result, with no formal backing by Democrats.

A former labor union leader and US Navy veteran, he is running again with a populist platform, appealing to the middle and working class, and he is seen as intriguing, with a possible chance to win.

North Carolina Republican Senator Thom Tillis is not seeking reelection, and former Democratic Governor Roy Cooper is the favorite to win the seat over Republican Michael Whatley, former North Carolina Republican Chairman, and also Republican National Chairman in 2024-2025.

Cooper was an exceptional governor in a state where the opposition Republicans often controlled the legislature, but he gained a reputation for principled leadership, and had a background as four term State Attorney General before his two terms as Governor. There is real optimism that Cooper can swing this state to the Democratic camp, with Cooper ahead in public opinion polls.

Ohio also is a state that Democrats are optimistic will swing their way in the Senate race, with former Senator Sherrod Brown, who served three terms, but lost his seat in 2024, trying for a comeback against appointed Senator Jon Husted, former Lieutenant Governor, who replaced Vice President JD Vance, when he was elected Vice President to Donald Trump in the Presidential Election of 2024.

Brown was considered one of the most liberal members of the Senate, and earlier had served in the House of Representatives and in the state legislature. Husted has been strongly conservative, and served as Secretary of State of Ohio before becoming Lieutenant Governor. It will be a tough race, but Democrats are hopeful that Brown can return to the Senate in the upcoming election. Polls indicate a very close race between Brown and Husted.

Finally, the crucial state of Texas, strongly Republican in recent decades, but having a three way primary in the Republican Party, of incumbent Senator John Cornyn, State Attorney General Ken Paxton, and Congressman Wesley Hunt.

Cornyn has been in the Senate for four terms, but is facing a serious challenge from the controversial and crooked Paxton, and African American Congressman Hunt. Cornyn has more support from the party and funding, but Paxton in particular could possibly upend the race, although his corruption is a significant issue, as he was impeached, although not convicted by the Texas legislature. Polls show an extremely close race for the nomination, with African American Congressman Hunt seen as a wild card.

The Democrats have an even more exciting race of outspoken African American Congresswoman Jasmine Crockett, and State Representative James Talarico. Either candidate would be an exciting addition to the Senate, with Crockett more controversial and outspoken, while Talarico brings a soothing brand of noncontroversial Christianity and idealism to the race. Talarico would be the youngest US Senator if he won the seat. There is something very inspiring to this author and blogger about Talarico, particularly.

There will be plenty of “fireworks” in Texas, with the state primaries coming in March. And were Crockett or Talarico to win the seat in November, almost certainly, the Senate would become a Democratic majority for the 120th Congress (2027-2029).
