None of this matters much. Legislation improving education, health care, climate change, energy, national security manufacturing are shortly going to all be in place. Inflation and supply chain issues (not really subject to government action) give some sign of easing. Unemployment is at an all time low. The markets are starting to recover so folks' retirement accounts should be in better shape, including pension plans. Crime is still up but is way below the peaks of 1970s and 1980s and the pandemic is under better control. Now it doesn't really matter who controls the Senate or House in 2023-24, since it's likely anything really despicable can be vetoed by the President. After Jan 2025, it may be another deal, but it remains to be seen. By then, some coastal cities may be under water part time, and some areas of the country may be simply too hot to live in. That's a potential challenge to the stability of the economy and quality of life, but there's little we can do about it now. Too damn late perhaps.
Needed legislation may need to be bipartisan, although the Republicans are out of practice

.
Sensible and non-conspiracy theorist people can sleep soundly for the next 2.5 years in all likelihood. Radical violent nutjobs can still cause local harm but the Republic has survived a narcissistic wildman as President and a would be insurrection has been largely put down.
Nowhere to go but up from here.
