Democrats lead the generic ballot by 9 points, ahead of 2018’s wave

On Oct 23, 2026, 11 days before Election Day, the Silver Bulletin average of generic ballot polls had Democrats ahead by 9.0 points. At the same point in 2018, the 538 average had Democrats ahead by 8.2 points, and they went on to win the national House vote by 8.6. At the same point in 2022, the 538 average had Republicans ahead by 0.6 points, and they won the House vote by 2.7.

The generic ballot asks people which party they would vote for in their House race, without naming candidates. It is the closest thing to a national poll of a midterm, and it is the indicator most often compared across cycles.

What it means

A 9-point Democratic lead 11 days out is larger than the lead Democrats held at the same point in 2018, the last midterm that produced a Democratic wave. In 2018 the average barely moved in the final stretch: from D+8.2 at 11 days out to D+8.6 on Election Day, which matched the final House vote of D+8.6.

The 2026 lead is also far from 2022’s position. Four years ago the average sat near a tie (R+0.6) at this point and drifted to R+1.2 by Election Day. On those two benchmarks, the 2026 environment looks closer to 2018 than to 2022.

Recent individual polls sit around the average. In the last 30 days the published polls include YouGov likely-voter samples at D+7 and D+9 and a New York Times/Siena College likely-voter poll at D+11, all ending Oct 19–20.

What it doesn’t mean

It is not a seat count. The national House vote and the number of seats each party wins are related but not the same, because seats depend on where votes fall, which seats are contested and how districts are drawn. A national lead of 9 points does not translate into a fixed number of seats.

It is not error-free. In 2022 the average was R+0.6 at 11 days out and R+1.2 on Election Day, while the House vote was R+2.7. Polls understated Republicans by about 2 points from this point in the campaign. An error of that size today would still leave Democrats ahead, but it shows the average can miss in one direction.

It is not one consistent series. The 2026 figure comes from the Silver Bulletin average; the 2018 and 2022 figures come from 538’s average. Both combine many polls and adjust for pollster differences, but they are built by different teams with different rules, so a gap of under a point between 2026 and 2018 is within the difference the methods alone could make.

It does not say who will turn out. Many polls in the average are of likely voters, but a likely-voter screen is an estimate of who will vote, and in a midterm turnout is lower and less predictable than in a presidential year.

How we checked

We took the Silver Bulletin generic ballot average as published on Oct 23, 2026, and 538’s historical generic ballot averages for 2018 and 2022. We aligned the three cycles by days before Election Day: “11 days out” is Oct 23, 2026, Oct 28, 2022 and Oct 26, 2018.

For the final House vote we used the national popular vote as published: D+8.6 in 2018 (Cook Political Report) and R+2.7 in 2022. Our own county-level build from MIT Election Data and Science Lab returns gives D+8.4 for 2018 and R+3.1 for 2022; the small gaps come from uncontested and missing districts in the precinct files, so we report the published figures.

Margins are Democratic share minus Republican share, in points. D+ means a Democratic lead and R+ a Republican one.
