With 35 US Senate races up for election in November, 2026, the following Democratic Senators are seen as having “safe” seats:
John Hickenlooper, Colorado
Chris Coons, Delaware
Cory Booker, New Jersey
Ben Ray Lujan, New Mexico
Jeff Merkley, Oregon
Jack Reed, Rhode Island
Mark Warner, Virginia
Also, Ed Markey, Massachusetts, who, however, is being challenged by fellow Democrat, Congressman Seth Moulton, mostly on the issue of age.
The following Senate seats that are Democratic are likely to remain so, but with challenges from Republicans:
(Dick Durbin), Illinois, who is retiring–with Congressman Raja Krishnamoorthi far ahead of competitors in fund raising and polling.
(Gary Peters), Michigan, who is retiring–with a hot three way race of Congresswoman Haley Stevens, who has the private support of Democratic Senate leadership; State Senator Mallory McMorrow; and former Wayne County, Michigan Health Director Abdul El-Sayed. Stevens is seen as centrist, while McMorrow and El-Sayed are seen as more progressive by comparison, and all three are 39-42 in age, so a new generation for sure, no matter who wins the nomination. All three are very close in public opinion polls, but Stevens seems to have a clearcut edge at this point.
(Jeanne Shaheen), New Hampshire, who is retiring–with Congressman Chris Pappas the only viable candidate for the Democrats–facing a likely challenge from former Republican Senator John Sununu.
Finally, the one most crucial race is Jon Ossoff of Georgia, who has the toughest race of all, to keep his seat. The youngest member of the Senate, he has been outstanding, but Georgia will be a tough state to win reelection in 2026, as it tends to be Republican oriented, except for the miracle that both Georgia Senators elected in 2021 are Democrats—Ossoff, and Raphael Warnock.
