Or at least seventy percent of the game (boldface mine):

Our estimate is that the voters who voted in the 2025 Supreme Court election backed Kamala Harris by 7 points in 2024. In other words, roughly 70% of Susan Crawford’s win margin was attributable to changes in who was voting, rather than changes in how people voted. While the persuasion she got would still have been enough to flip the state with a November 2024 electorate (which was Trump +1), the landslide victory largely came down to a big turnout advantage…

The geographic differences confirm preexisting patterns of educated white voters punching above their weight for Democrats, and the impact of the low-propensity voter realignment is especially visible in the western part of the state. Looking forward to 2026, this coalition that Wisconsin Democrats have arranged could prove crucial to flipping the state legislature and holding their existing statewide offices.

Roughly a year ago, some asshole with a blog noted:

And I’m old enough to remember when Democrats were the party of low-propensity voters. In other words, Democrats used to want high levels of turnout because unlikely/less likely voters were disproportionately Democratic…

A side effect of this, which isn’t relevant for 2024, is that Democrats will likely do very well in many off-year elections–and those elections do count–a majority built in off-year elections can pass legislation just as well as one built in a presidential year.

The Wisconsin judicial election seems to back that up:

These turnout dynamics in Wisconsin invert previous Democratic political thought. Previously, low-propensity working class voters of all races showing up in presidential years used to benefit Democrats. In midterms, those voters would stay home, usually giving Republicans an advantage. But this has not been the case of late — in 2022, 2023, and 2025, the voters that showed up were much more Democratic than the partisanship of the state.

Like I wrote, votes cast by senators and congressmen elected in off-year elections count as much as they do when cast by presidential year winners. But Democrats also need to realize that they have to rally their voters, try to get some of the highly unlikely voters and discourage Republican voters to win in general elections.
