Seems an unlikely chain of events. Biden's determination at keeping a steady aim on his foot are likely to continue, thereby staking the Democrats to an early lead at losing both the House and Senate in 2022 and the White House in 2024.
While the Democrats self-destruct the Republicans are making a determined effort at making it possible for them to overturn elections. They are busy replacing the procedures governing elections and the officials who oversee them in a way that benefits themselves.
Republicans are far more motivated than Democrats to take charge of the electoral machinery. Democrats working on elections believe the result of their efforts will be clean and fair elections. Republicans believe the result will be that their guys win. Of course Republicans are more motivated.
