Is a 6-Week Abortion Ban a Disaster for DeSantis? Two Theories.

Theory No. 1: It’s about demographics.

Abortion is relatively unpopular in states where today’s Republicans successfully banned abortion, like Texas or Georgia. These states tend to be relatively religious states in the South. There aren’t many of the secular, white, college-educated liberal Democrats who could bring about a “Roevember” backlash.

There seems to be a lot to this theory. Not only does it explain many of the cases in question, but it also fits a broader pattern from last November: Democratic strength in the House vote was somewhat correlated with support for abortion (though big Democratic failures in New York and California stand out as obvious exceptions).

But this theory doesn’t quite explain everything. In particular, it doesn’t work outside the South, including in places like Ohio or Wisconsin, where we know the right to abortion is popular. That’s where it’s important to notice my qualifier: where today’s Republicans successfully banned abortion. If demographics are the predominant explanation, then the Republican resilience in the North must be because voters simply didn’t hold them responsible for banning abortion. Democrats could hope Republicans will pay a greater political cost when they unequivocally restrict abortion, like what Mr. DeSantis is doing now in Florida.

Theory No. 2: When abortion is the most important issue.

This is what I’ll call the salience theory: It takes a special set of circumstances for Democrats to make abortion the most important issue to voters, like a Wisconsin Supreme Court candidate who promises to represent the decisive vote to legalize abortion when an abortion case is pending before the court, or a Michigan referendum that explicitly decides the future of abortion in a state.

As with the demographics theory, the salience theory is also consistent with polling and the general story of the 2022 midterms. Only a sliver of voters said abortion was the most important issue, not because abortion rights wasn’t important to them but because there were lots of other genuinely important issues at stake — the economy and inflation, crime, guns, democracy, immigration, and so on. With so many other issues, it makes sense that abortion plays only a marginal role in vote choice unless a distinct set of circumstances focuses the electorate on abortion alone.

The salience theory also fits one of the patterns of the election: the highly localized results. There were states where Democrats excelled, like Michigan or Pennsylvania, even as they struggled in California or New York. Where Democrats did well, they had the fodder to focus voters on one of their best issues, like attacking stop-the-steal candidates. Where they struggled, Republicans managed to focus the electorate on an issue like crime (democracy or abortion seemed less important).

It’s worth emphasizing that the salience theory doesn’t mean that abortion as an issue didn’t help Democrats in 2022. If Roe hadn’t been overturned, abortion would have been less salient everywhere and perhaps Democrats would have fared a bit worse across the board. But it would mean that Republican support for an abortion ban is not, on its own, sufficient to make abortion the predominant issue and bring stiff political costs to conservatives.

While this theory offers better news for Mr. DeSantis, it would nonetheless contain a lesson for Democrats: It seems they would be wise to find creative ways to keep the electorate focused on abortion. State referendums might be one option, much as Republicans put same-sex marriage on the ballot in 2004. A campaign to pass federal abortion legislation might be another path as well.
