I'm pessimistic about Democratic chances in 2022 to maintain the House majority. The Senate may be easier.
Here's a map for the Senate, showing Pennsylvania as a tossup and Georgia as leaning Democratic. I'm not sure about Georgia; the Republicans are working on changing the rules for voting. On the other hand, Sen. Warnock did do better than Ossoff.
In the House give the Republicans a pickup of 8-10 seats from redistricting and add in the historical loss by the majority party in mid-year elections and things look grim.
It's possible that Biden and the Democrats do a great job on covid and the economy, foreign affairs don't erupt into anything major, and the Republicans experience a lot of intra-party conflict resulting in weak candidates. It's possible, but I'm not hopeful.
