I think there's a decent chance the Democrats will gain control of the Senate in November. That would help immensely. We'll have to look out for the midterms though. Between Trump and Covid-19, things are likely to be in a mess for the next couple of years, and the Repubs will certainly be trying to blame the Democrats for all of it.
An even more scary thought. If Trump loses in November, which I now think is very likely, he will be eligible to run in 2024.
I think the big worry is what the current Senate will try to do between the election and the installation in January of the newly elected Senators. Moscow Mitch has already said he will confirm as many judges as possible this year.
And never forget that Trump will remain President until Jan. 20. He can do even more long-term damage on his own out of sheer rage.
