The author discusses the competitive Senate races in the 2026 election cycle using their FLIPR forecast model, which currently favors Democrats but still considers the Senate to be a toss-up. According to the model, Democrats need to net at least four seats from states that Donald Trump carried in 2024, with the national popular vote being a key indicator of their chances. The article specifically highlights seven key Senate races, including Ohio and Michigan, where polls show contradictory results but can be influenced by various factors such as candidate strength and fundamentals. These seven races have a combined 71% chance of deciding which party controls the Senate after 2026.

Story summary
The US Senate has become unexpectedly competitive ahead of the November elections, with Democrats potentially on track to win control from Republicans. 74 days remain until election day and the party only needs to flip three seats to gain control. Historically, a party out of the White House tends to gain more than two dozen seats in midterm elections, which suggests Democrats have a good chance. The biggest question now is whether they can capitalize on this momentum in key states such as Ohio, Michigan, and North Carolina, where polls show mixed results. In Ohio, Democrat Sherrod Brown is leading by 8 points, while in Michigan, Democrat Abdul El-Sayed trails by 4 points according to recent polls. The Senate currently has 53 Republicans and Democrats need to net at least four seats to take control.

But while it currently rates the House as “likely D”, the Senate is still in true tossup territory.1
Why is the upper chamber so competitive?

Well, it’s pretty simple.

True, the GOP has few solid pickup opportunities, but they already have 53 senators and a tie-breaking VP.

Just this week, Fox News released polls showing Democrat Sherrod Brown leading by 8 points in Ohio — but Abdul El-Sayed trailing by 4 points in Michigan.

In the context of a presidential race, that wouldn’t make much sense, since Michigan is the considerably bluer state.

Michigan → make → sense
Particularly if you believe that moderation matters, El-Sayed is arguably a weaker candidate than Brown.2

Outcomes in congressional races are correlated with one another, although considerably less so than in presidential races.

So for my first model talk of the 2026 cycle, I’m bringing back a popular article format from 2024 and taking you on a tour of the seven most likely Senate tipping-point states (plus some honorable mentions at the end).

For purposes of this article, we’ve promoted North Carolina from that tier into the Big 7.
asserted
we → promote → Big
Our model doesn’t think NC is a particularly likely tipping point because it’s pretty confident that Democrat Roy Cooper will win, perhaps comfortably.
asserted
Cooper → think → ?
Still, nobody should take North Carolina too much for granted: it has only voted for Democrats once for president since 1976 (it went for Barack Obama in 2008) and has frequently been a close-but-not-quite state for Democrats in federal races.
