Pro-Trump Wins in Blue States Threaten GOP Hopes in November

In your typical midterm election with an unpopular Democratic president, you’d expect Republicans to be flying high. But the evidence is mounting that the national political environment right now actually leans toward Democrats.

On Tuesday, Democrat Pat Ryan defeated Republican Marc Molinaro in a special election for New York’s swingy 19th Congressional District by 2 percentage points, 51 percent to 49 percent. At the same time, Republican Joe Sempolinski defeated Democrat Max Della Pia by a closer-than-expected margin of 7 points in the special election for New York’s solid-red 23rd District. On their own, these elections could be dismissed as flukes, chalked up to local factors or particularly strong or weak candidates. But given how these two elections are part of a larger pattern of good results for Democrats over the last two months, they suddenly look a lot more like signal than noise.

We at FiveThirtyEight often track the results of special elections (i.e., elections that occur at unusual times because an office unexpectedly becomes vacant) because of the hints they provide to the national mood. When a party consistently does well in special elections — defined not by winning or losing, but by outperforming a state or district’s baseline partisanship — it’s often a sign that the national political environment favors that party, and is therefore a good omen for that party in the upcoming regular general election.

Up until mid-June, special elections for the U.S. House during the Biden presidency were pointing to a national political environment that was neutral or a little bit Republican-leaning. On average, Republicans did 2 points better in those elections than you’d expect based on the districts’ FiveThirtyEight partisan leans. That all changed, though, starting in late June — immediately after the Supreme Court issued its decision in Dobbs v. Jackson, overturning the constitutional right to abortion. There have been four first-past-the-post special House elections since that decision, and Democrats have outperformed their expected margins in those elections by an average of 9 points.

The pattern of Democratic overperformance started with the June 28 special election in Nebraska’s 1st District. No one expected this district with an R+17 partisan lean to be competitive, but it was a nailbiter: Republicans won by just 5 points. Then, on Aug. 9, Democrats came even closer (within 4 points) in a similarly red district, Minnesota’s 1st (partisan lean R+15). This was still just two data points, though. But then, of course, came Tuesday’s special elections in New York. In the 19th District, Democrats’ winning margin was 6 points better than the district’s R+4 partisan lean, and in the 23rd District, it was 9 points better.

The bottom line is these two data points put to rest any notion that the Nebraska and Minnesota results were a fluke; special-election results are clearly indicating that the political winds are now at Democrats’ backs. And it’s not just special-election results. Democrats and their allies have also done well in other, non-special elections since Dobbs. The results of Washington’s top-two primaries (which, unusually, pit Democrats and Republicans against each other and have historically done a good job predicting the November elections) were not consistent with past “red wave” midterm elections. And a Kansas ballot measure that would have clarified that the state constitution does not protect abortion rights failed by a large, 18-point margin despite the state’s conservative leanings.

Moreover, one of the best indicators we have of the national environment in a midterm year has also gotten better for Democrats since Dobbs — although it is currently showing more of a neutral political environment than a Democratic-leaning one. On the day of the Dobbs decision, Republicans led polls of the generic congressional ballot, or polls that ask Americans which party they plan to support for Congress, by 2.3 points, according to FiveThirtyEight’s average. But since then, Democrats have gained 2.7 points, and on Wednesday,3 they hold a small lead in these polls.

This is unusual, given that the polls usually get worse, not better, for the president’s party as a midterm election draws closer. That could be a sign that 2022 could be the rare midterm that bucks the usual trend of the president’s party getting a “shellacking.” And if so, Democrats may have the Supreme Court to thank. Correlation isn’t causation, but given the precise timing (Republicans overperformed in special elections on June 7 and June 14, then Democrats started their hot streak on June 28), it seems quite likely that the Dobbs decision is responsible for the shift in the political environment.

It’s also worth noting there has been other good news for Democrats in recent weeks: They passed the Inflation Reduction Act, a major climate, health-care and tax bill. Gas prices have significantly declined, potentially weakening the potency of Republican attacks on inflation. And President Biden’s approval rating has slowly been ticking back up. All these things could have contributed to Democrats’ special-election success too.

But none of this is a guarantee of Democratic success in the midterms. As quickly as those developments broke, others — perhaps better for Republicans — can replace them. Of course, events thus far have suggested we aren’t in a typical midterm situation; for instance, maybe the switch from registered-voter polls to likely-voter polls won’t benefit Republicans as much as expected because Democrats are so fired up. But there are still two and a half months until Election Day. And while it’s hard to deny that Democrats have the momentum right now, it’s an open question of whether they can sustain it.
