Heading into the final two days before the 2022 midterm elections, it is clear to me that the Republican Party has the momentum and this will essentially be a normal midterm, with one caveat: It appears that Democratic turnout will be higher than could normally be expected in a midterm with a Democratic president, which will blunt Republican gains somewhat and possibly enable them to preserve their tenuous 50-50 hold on the U.S. Senate.
But even though Republicans appear unlikely to get the 34 or 35 seats the “out” party could expect to pick up in an average midterm election, I still expect almost every U.S. House seat Joe Biden won by less than 8% in 2020 to flip to the GOP. As such, I expect Republicans to pick up 23 U.S. House seats and take the majority by a 236-199 margin.
I didn’t just pick this number out of a hat, and when I made my first projections in the spring, it was higher. At that time, I expected Republicans to flip virtually every district Biden won by less than 12%, which I based on Democratic underperformance, relative to 2017, in the governors’ races in Virginia and New Jersey last year.
After the Dobbs decision overturning Roe v. Wade, I noted that Democratic over performance in special elections from that point was significant enough that I changed my projection to Democrats losing virtually every Biden +3 seat. But with momentum clearly turning back to the Republicans in the last month or two, I expect to end up somewhere in the middle between those two extremes. With a couple of exceptions, I am projecting Republicans to win any Biden House seat of +8 or less. I expect with close to 100% certainty that Republicans will control a majority of the House in January 2023.
The Senate, I feel less confident about. On one hand, Republicans have hurt themselves badly by picking a number of really bad candidates. On the other hand, the only five Senate races that appear to be in doubt at this point are four seats currently held by Democrats and only one seat currently held by a Republican. Democrats would need to win four of those five seats just to stay at 50-50. In a year in which I expect Republicans to gain, it is hard to imagine that Republicans would win only one of these five super-competitive seats. Had the GOP chosen better candidates in Pennsylvania, Georgia and New Hampshire, I’d be projecting the GOP to pick up at least two seats and most likely three. And those dynamics might still hold, possibly propelling two or three of those really awful Republican candidates into the Senate. Right now, I’m calling it 50-49 GOP with Georgia going to a runoff, but it’s far likelier that it might be 51 or 52 seats for the Republicans than it is that Democrats will do any better than 50-50. In short, the dynamics tell me to expect the Republicans to get 51 Senate seats, but it’s just hard for me to see where they get that 51st seat.
On average, my projections since 2006 have been within seven seats in the House and 1.375 seats in the Senate. Based on my historical error rate, one could expect a Republican House majority of anywhere from 229-206 to 243-192, and a Senate that contains anything from a 52-48 Democratic edge to a 52-48 Republican edge.
I also make projections at the state level, and those are all available in the attached chart.
