We’re approaching Labor Day — which has traditionally been considered the “real” starting point of midterm election campaigns.
asserted
which → approach → campaigns
You’ll often hear a narrative that goes something like this: voters only get serious after Labor Day.
asserted
voters → hear → Day
They get back to their grind, their kids go back to school, and they finally start paying attention to politics (and football).
asserted
they → get → politics
So, you can’t really trust anything going on in the polls before then.
asserted
you → trust → polls
Selfishly, we’d love it if this campaign were only just getting started and there were wild gyrations in the polls and dramatic late swings in the race.
asserted
campaign → love → race
Those tend to generate a lot of interest in the work we do here at Silver Bulletin.
asserted
we → tend → Bulletin
But as responsible forecasters, we have to say: that’s usually not how congressional elections work, and that narrative is outdated in more than one way.
asserted
narrative → have → way
For one thing, school starts in August in the large majority of the country.
asserted
school → start → country
More importantly for our purposes, though, midterm races in the modern era tend not to change all that much between Labor Day and Election Day.
asserted
races → tend → Day
The topline numbers in FLIPR, our midterm election model, have been quite steady since we launched it a few weeks ago, and we’d probably expect them to stay that way.
asserted
them → launch → it
Let us clarify what we mean by this claim, because it would be easy to misconstrue this post.
uncertain
it → let → post
We don’t mean that polls will be perfectly accurate.
asserted
polls → mean → ?
Obviously, you don’t need to go back very far to see examples of systematic, correlated polling errors — hello, 2016 and 2020 (and to a lesser extent 2024) — though note those were all presidential years rather than midterms.
asserted
those → need → extent
But how accurate the final polls are on Election Day is a different question from how much they drift or swing between September and November.
asserted
they → drift → September
We also don’t mean there won’t be major shifts in individual races.
asserted
We → mean → races
Some states haven’t even held their primaries yet.
asserted
states → hold → primaries
And some important races have relatively little polling.
asserted
races → have → polling
A new poll in Michigan or Maine or South Carolina or Alaska pretty much affects that state and that state only.
asserted
poll → affect → state
Finally, it’s worth remembering that even small swings matter; our model is pretty sensitive at the margins.
asserted
model → ’ → margins
It’s probably going to be a blue year, but there are different shades of blue.
asserted
It → go → blue
But whether the 2026 national environment ends up looking closer to a pale eggshell or a dark navy will have massive implications for whether the Democratic Party’s year is spectacular or just okay.
asserted
year → end → implications
Democrats will need to win the popular vote by at least 3 points to be favored to win the House, and by at least 4 to 5 points if they want a double-digit majority.
asserted
they → need → majority
Even if they do win, this will affect how many House seats they pick up.
asserted
they → win → seats
(One can only assume that Hakeem Jeffries will want to avoid the problems his Republican counterparts are currently dealing with while trying to manage the slimmest House majority.
asserted
counterparts → assume → majority
Several traditionally Republican states — such as Texas and Ohio — lean slightly toward Democrats in large part because of favorable candidate quality matchups.
asserted
states → lean → matchups
But the national environment moving just a few points to the left would make Democrats clear favorites in those races.
asserted
Democrats → move → races
A shift of even a couple of points in the other direction would spell near-certain doom for Democrats’ chances of sweeping both chambers.
asserted
shift → spell → chambers
So yes, we hope you’ll keep checking in on FLIPR’s forecast.
asserted
you → hope → forecast
However, we’d probably bet against learning all that much more about the national environment until votes actually start getting counted on Nov. 3.
asserted
votes → bet → Nov.
This chart, drawn from our historic generic ballot averages, tells you most of what you need to know:

you → draw → what
