Decided to use a format similar to [this prediction](https://www.reddit.com/r/YAPms/comments/1szxbip/my_official_2026_senate_prediction/) by u/PalmettoPolitics this time. This is also the first time I decided to have more specific margin estimates for the 2026 US Senate race. That said, since this is 6 months before the general election, those could change very easily.

**Margins:**

* Safe: 15% or more
* Solid: 10-15%
* Likely: 5-10%
* Lean: 1-5%
* Tilt: 1% or less

**Montana:**

This is kind of hard for me to determine, since I don’t know what impact the independent, Seth Bodnar, will have on this race. Could he take votes from the D, keeping this over 15%? Or could he take from both parties? I’m putting it as Solid R for now since Kurt Alme doesn’t have an incumbency advantage.

*Current margin: Alme (R) +14*

**Mississippi:**

Mississippi is a very racially polarized state, so I struggle to see it being that competitive. Even Brandon Presley couldn’t win a Gov race against a very unpopular incumbent. That said, Cindy Hyde-Smith is a weak candidate who won only by single digits in the 2018 special election and 2020, so even though Scott Colom is no Mike Espy, he should keep it under 15%.

*Current margin: Hyde-Smith (R) +12*

**Minnesota:**

I was debating whether to have this as Likely or Solid D, given that this is an open seat, and Royce White is unlikely to win the GOP primary. But now, I’m leaning towards the latter, given the recent ICE controversies in Minnesota. Klobuchar’s strong performance in the Gov race could also help out Flanagan to some degree, and Tina Smith was able to win the 2018 MN special election by double digits.

*Current margin: Flanagan (D) +10.5*

**South Carolina:**

The only polls out of this race so far are Democrat internals, I don’t see the race getting to R+5 or R+6. Polls way overestimated Jaime Harrison in 2020, and he still lost by double digits. In this environment, it’s likely to be closer, but not by that much.

*Current margin: Graham (R) +9*

**Kansas:**

Unless Sharice Davids runs for this seat, I doubt Kansas’ US Senate race will be that competitive. Although Kansas is a left-trending state, Marshall isn’t disliked nearly enough for the race to be particularly close. Even so, the trends in this state are enough for me to have it in the single digits.

*Current margin: Marshall (R) +8.5*

**Florida:**

While Florida has moved right in recent years, it’s possible that some of the Latino reversion we saw in 2025 happens here to some degree. It’s not enough to make Florida a battleground again, but it’s yet another race I expect to see in the single digits. Sadly for Florida Democrats, their party still hasn’t really recovered.

*Current margin: Moody (R) +8*

**North Carolina:**

This is Democrat’s easiest pickup by far, with it being as close to a guarantee as you can get for a battleground swing state Senate election. Michael Whatley is a generic R with little name recognition, and Roy Cooper is a popular former governor within the state. I originally thought he’d underperform Ossoff due to not being an incumbent US Senator, but North Carolina is a bit more elastic, and Whatley’s low name recognition could give Cooper a greater opportunity for a big win.

*Current margin: Cooper (D) +6.5*

**New Hampshire:**

I see some people say this race could be competitive because of John Sununu running, but I don’t agree, for a few reasons. One, Chris Pappas is an overperformer. Two, this is a very Democratic-friendly national environment. And three, John Sununu is more recognizable than most Rs in New Hampshire, but he’s not his brother. Pappas should win with little trouble.

*Current margin: Pappas (D) +6*

**Georgia:**

I’ve debated on whether this race should be Lean or Likely D for a while, given racial polarization, and how the state isn’t as elastic as states in the Rust Belt. That said, Mike Collins (Who will likely be the R nominee) is a rather weak opponent, Ossoff is a strong incumbent, Georgia is a left-trending state, and Georgia is capable of large swings (as shown from 2016 to 2020). This could change, but I lean a bit more towards Likely D for this race.

*Current margin: Ossoff (D) +5.25*

**Iowa:**

Despite Joni Ernst’s decision to retire, Democrats are performing better than expected in the polls, with Wahls and Turek leading in a recent Echelon Insights (R) poll. I don’t think either could beat Hinson, though, since she’s a fairly strong candidate and much better than Joni Ernst. Still, the national environment should propel whoever wins the D primary enough to give Hinson somewhat of a tough fight.

*Current margin: Hinson (R) +4.5*

**Nebraska:**

I see a very wide range of views on this race, from “Osborn is in a much better national environment! He’ll win this time!” to “Osborn won’t pull off the same magic a second time! He’ll lose by more than in 2024!”, and my view is somewhere in-between. I do think the national environment will help out Osborn a lot, though Ricketts isn’t as disliked as Deb Fischer. If he does distinguish himself enough from Democrats, he could have a chance, but I think it’s more likely that he does just well enough to give Ricketts a tougher fight than Fischer faced two years prior.

*Current margin: Ricketts (R) +4*

**Michigan:**

This one is really hard to predict because Dem primary polls are all over the place. El-Sayed is likely the weakest of the three, given his controversies and poor campaigning that would likely push away moderates. McMorrow isn’t exactly remarkable, but she’s the strongest candidate due to being a balance between moderates and progressives. I’d say El-Sayed is the only one in any real danger of losing, though the national environment could still save him. McMorrow, on the other hand, is the one who has the best shot of winning by over 5%. To balance things out, I’m keeping the race as Lean D. But it’s easily the GOP’s most likely pickup chance, or at least the best chance to overperform.

*Current margin: Average (D) +3.33*

* *McMorrow (D) +5*
* *Stevens (D) +3.5*
* *El-Sayed (D) +1.5*

**Maine:**

I’ve been iffy on this race for a while, though I’ve maintained that Democrats have the edge. Collins has overperformed before (2020), but partisanship is much higher, the national environment is likely to be much bluer than in 2020, and Platner is a far stronger opponent than Gideon. It’s possible that a truly disqualifying scandal comes out that damages Platner, but I strongly doubt it. If that doesn’t happen, Platner has a very good chance of beating Collins. Still, I’m hesitant to say for sure because Maine polls are unreliable, and Collins has beaten the odds before. She’s unfavored, but not DOA. Ultimately, it will come down to how independents vote.

*Current margin: Platner (D) +2.5*

**Alaska:**

If you had told me a few months ago that Peltola would be leading in the polls by a good margin, including in Alaska Survey Research, I would be surprised. But Sullivan’s approvals are low, Peltola is running a great, localized campaign, and Peltola’s lead isn’t only in D internals. While I don’t believe her lead will be as large as some polls say, she can absolutely win this race.

*Current margin: Peltola (D) +1.5*

**Texas:**

I see this as a slightly bluer 2018 - Talarico is arguably a stronger Dem than Beto O’Rourke, and Ken Paxton is a controversial, scandal-plagued candidate who’s even worse than Ted Cruz. Even so, the odds of Talarico winning aren’t extremely high. Talarico is fairly liberal, and he only really has a chance because of the national environment, and Paxon being horrible. The last time a Democrat was elected to the US Senate was Lloyd Bentsen winning a fourth term in 1988. It would take a lot for that Republican streak to come to an end.

*Current margin: Paxton (R) +1.5*

**Ohio:**

While Husted is leading in the polls, given some of his recent controversies, as well as Brown’s own status as a former US Senator in the state, I imagine this race will be extremely close. Brown can absolutely win, though I still give it to Husted very slightly because Brown doesn’t have the incumbency advantage he had in 2024, and Ohio’s no Alaska.

*Current margin: Husted (R) +0.5*
