The GOP didn’t really lose the 2020 election; Donald Trump did. The swing voters in the electorate were tired of his chaos in general, and his incoherent response to the virus in particular. By 2024, however, the voters were suffering from collective amnesia about 2020; all they could remember was the good times of 2019. Biden, on the other hand, was unjustly held completely responsible for the inflation of 2021-2023. The transactional swing voters–about 10 percent of the electorate–went Trump’s way, and the rest is history.
The pendulum swung back on Tuesday, as any reasonable person would have predicted. It will probably continue swinging left unless the economy improves, which, GOP optimists notwithstanding, is unlikely. The Democrats will probably win seats in both houses in 2026 if the election is free and fair. Then what? Trump will be a lame duck, Vance will be required to embrace every part of his unpopular legacy, and the base will be pulled in a variety of different directions by candidates outside of the administration. It will make for fascinating viewing.
