Political science-based forecasting models offer a clear prediction for the 2022 midterm elections – the results will be very bad for Democrats. Based solely on the fundamentals like the state of the economy, the type of election (ie midterm) and having an unpopular Democrat in the White House, a model by political scientists Charles Tien and Michael Lewis-Beck, generated months before 8 November, predicts a 44-seat loss for Democrats in the House and a five-seat loss for Democrats in the Senate.

The forecasting models produced by FiveThirtyEight are not quite as grim about the prospects for Democrats, predicting that the party will most likely lose majority control of the House of Representatives, but have a small (and shrinking) edge in holding on to their minuscule advantage in the Senate. Unlike the political science models, FiveThirtyEight’s predictions also incorporate polling data and therefore pick up on the ground-level reality that Republicans have put forth weak candidates in key races.

But there is a plausible case to be made that even models incorporating polling data are underestimating Democratic strength in the 2022 midterms. The issue of abortion may help Democrats in two important ways that are not being picked up in either of the models discussed above.

Predicting the outcome of elections is considerably more difficult than other types of polling (eg issue polling), as it requires making assumptions about who is actually going to turn out to vote. Among these well-founded assumptions is that young people have the lowest turnout of all age groups – especially so in midterm elections. Thus current likely voter models assume that young people will once again underperform as voters in 2022.

For those who have interacted with young women recently – the anger about the Dobbs decision is undeniable. Outrage at the idea that “old white men” are making decisions about their bodies has made abortion a priority for young women. A recent poll of Gen Z Americans in swing states supports this, providing empirical evidence that young people are energized to vote and continue to rank abortion as their top issue, even while the issue has slipped in importance for older Americans. Young people’s passion on issues has failed to translate into actual action in the voting booth in the past; however, if young pro-choice women actually do turn out in higher numbers than forecasting models are expecting, this could provide a multi-point bounce to Democratic candidates in key House and Senate races.

Additionally in our research we found there are a lot of cross-pressured Republicans on the question of abortion legality. While there are a small number of Democrats who hold positions on abortion in tension with their party – eg less than 10% approve the overturning of Roe v Wade – the percentage of Republicans uncomfortable with their party’s policies on abortion reaches anywhere from 30-50%. When abortion policy was more or less settled law, it was easy for cross-pressured Republicans to ignore the conflict between their party’s position and their own, but now that Republicans are enacting highly restrictive laws and outright abortion bans, such contradictions will be harder to ignore. How will cross-pressured Republicans respond?

The Kansas referendum over the summer suggests that the threat of abortion bans has the power to mobilize low-propensity voters and entice cross-pressured Republicans to abandon their party’s position. Voting for a Democratic candidate, however, is not as likely as voting in disagreement with one’s party on a referendum, especially in today’s polarized climate. The more likely possibility is that at least some cross-pressured Republicans may simply opt out of the electoral process.

Losing the House and especially the Senate would be a major political blow for the Democrats with important and lasting policy consequences, but should that happen, the impact of the Dobbs decision will likely have staved off much larger losses. And should the Democrats defy historical odds and hold on to the House, or, more likely, the Senate, they will almost surely have the Dobbs decision to thank and its ability to mobilize young voters and to demobilize cross-pressured Republicans.
