Silver Bulletin discusses the likelihood that Republicans could maintain control of the U.S. Senate despite Democrats' current momentum. According to their model, there's about a one-in-four probability that Republicans will hold onto the Senate by either limiting Democratic gains or flipping some Democratic-held seats. The article notes historical examples where significant seat changes occurred in both directions during midterms but emphasizes recent trends showing fewer competitive races and less ticket-splitting due to increased political polarization.

Story summary
Democrats currently have an edge in winning control of the Senate, according to Silver Bulletin's analysis. The model predicts that Republicans still have a roughly 25% chance of maintaining their current status by either preventing Democrats from gaining the necessary four seats or flipping one or more Democratic-held seats. Historically, Senate races used to see significant back-and-forth between parties; for instance, in the 1978 election, Republicans gained eight seats while Democrats flipped five, resulting in a net gain of three Republican seats despite Democrats retaining overall control. However, recent trends indicate fewer competitive states and less ticket-splitting, making race outcomes more predictable based on presidential voting patterns and weakening "candidate effects" like incumbency.

Generally, when a party is ahead in our forecast, we’ll highlight why our model thinks they’re winning.
asserted
they → highlight → forecast
Democrats have the better hand to play in the Senate; that’s been clear for a couple of weeks now.
asserted
that → have → weeks
At the same time, we try to cover our bases.

FLIPR’s forecasts are probabilistic, and we feel a duty to explain the downside and upside scenarios.

There remains a very real chance — about 1 in 4 — that Republicans keep the Senate despite Democrats’ seeming momentum.
asserted
Republicans → remain → momentum
And they have two basic ways they can do that: by holding Democrats to fewer than the four pickups they need, or by “stealing” one or more currently D-held seats.
asserted
they → have → seats
Alternatively, Democrats could still win the Senate even if they do lose some of their own seats by flipping more than four GOP-held states.
uncertain
they → win → states
Senate seats used to flip in both directions in the midterms.
asserted
seats → use → midterms
The 1978 election was the most absurd example: Republicans picked up eight Senate seats from Democrats (dark red) while Democrats flipped five seats to their side (dark blue).
asserted
Democrats → pick → side
Not a bad night, but Democrats retained a clear majority.
asserted
Democrats → retain → majority
However, in the past five midterms, a “double flip” has happened only once, in 2018.
asserted
flip → happen → 2018
On the surface, that looks like a really weird result.
asserted
that → look → result
Democrats won the popular vote for the U.S. House by more than 8 points, flipping dozens of seats in the process.
asserted
Democrats → win → process
They also flipped GOP Senate seats in Arizona and Nevada.
asserted
They → flip → Arizona
But they lost four Senate seats of their own: North Dakota, Missouri, Indiana and Florida.
asserted
they → lose → own
This seeming weirdness, though, was well predicted by models.
asserted
weirdness → seem → models
Senators serve six-year terms, of course, and that’s an eternity in politics.
asserted
that → serve → politics
Their terms straddled the election of Donald Trump, whose win signaled increasing political polarization and more specifically, a growing divide between college-educated voters in the cities and white working-class voters in the rural heartland.
asserted
win → straddle → heartland
Indiana, North Dakota and Missouri fit the pattern, with the red shift among rural whites outweighing the strongly blue background environment.
asserted
shift → fit → environment
Florida didn’t so much, but Bill Nelson’s loss there marked the beginning of a death spiral for Democrats in the state.
asserted
loss → do → state
I won’t spend much more time on why “double flips” are becoming less common because you probably know the story.
asserted
you → spend → story
Perpetually increasing polarization means that: 1) fewer states are competitive; 2) there’s less and less ticket-splitting, so races for Congress are more predictable based on presidential voting and 3) “candidate effects,” including incumbency, are weaker, so there’s less opportunity for a candidate with strong personal qualities to overcome the partisan tide.
asserted
candidate → increase → tide
Instead, let’s focus on these questions: 1) What is the chance of a “double flip” happening this year in the Senate, with both parties picking up at least one seat?
asserted
parties → let → seat
2) How screwed are Democrats if this happens: could they plausibly lose one of their own seats and still take over the Senate?
uncertain
they → happen → Senate
3) What should we think about Minnesota in particular, where Democratic Lt. Gov. Peggy Flanagan is in a surprisingly close race in polls against former NFL sideline reporter Michele Tafoya?
asserted
Flanagan → think → Tafoya
A double flip is plausible this year, but not a good bet at even money
This part of the equation is easy: Democrats are extremely likely to pick up at least one currently Republican-held seat.
asserted
Democrats → pick → seat
