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!

Four Challenging Senate Races For 2026 For Democrats

Several states with Republican Senate seats up for 2026 will be a challenge for Democrats, with them needing at least a gain of four seats, assuming the party keeps all of the seats they have coming up for reelection, in order to regain control of the US Senate in 2027.

This includes the states of:

Alaska
Iowa
Kentucky
Maine
Nebraska
North Carolina
Ohio
Texas

Today, there will be examination and analysis of the first four races listed above, with a later article on the latter four states.

In Alaska, native American former Congresswoman Mary Peltola is challenging Republican Senator Dan Sullivan, and this is believed to be a potential gain for Democrats, who see her race as the crucial one on the road to a Democratic majority in the Senate.

In Iowa, Senator Joni Ernst is retiring, and Iowa Congresswoman Ashley Hinson is favored as the Republican nominee, seen as having an edge in a state that has trended Republican in recent times.

However, there are two Democrats who have drawn interest—Zach Wahls, who became noticed 15 years ago when he openly supported his lesbian parents, and would end up in the Iowa state legislature, as a liberal activist; and Josh Turek, born with spina bifida, but while being in a wheelchair for his lifetime, has been a competitor in wheelchair basketball sports, along with service in the Iowa legislature. Wahls is seen as more progressive, while Turek is seen as more moderate in views.

Kentucky, a strongly Republican state, is choosing a successor to long term Senator Mitch McConnell, who had been both Senate Majority Leader and Senate Minority Leader. The Republican favorite is former State Attorney General Daniel Cameron, but challenged by Congressman Andy Barr, one of the most extreme right wing members of the Republican Party in Congress.

Democrats have two former contenders for the Senate—Amy McGrath, former Marine fighter pilot; and Charles Booker, former state legislator. Sadly, it would be a major upset if either Democrat won the Senate seat.

The state of Maine will have the most hotly contested election for the Senate, with Republican incumbent Susan Collins, in her 30th year in the Senate, and having a moderate image, but under attack by both her own party, including Donald Trump, but also Democrats who see a great opportunity to take this seat.

Collins is in her mid 70s, and her two Democratic opponents are sitting Governor Janet Mills, who would be, at 79, the oldest first term US Senator in history, if she won; and Graham Platner, oyster farmer, harbor master, and military veteran, who has become controversial for his past statements, his chest tattoo, and his perceived extreme utterances on a multitude of issues.

Polls indicate a very close competition between Mills and Planter, and between either of them and Collins, and this could be the tipping point election for control of the Senate in 2027.

At this point, the states of Alaska and Maine seem potential gains for the Democrats, with some possibility in Iowa, but unlikely any chance to win in Kentucky!
