At this rate, it will be possible for the GOP to take over the House, next year. They are, already, very close to having a political majority there. There are a handful of political races where it looks like the GOP candidate for a House seat had their victory taken away from them. Ditto, John James in his U.S. Senate race.
And what do you suppose they'd do with it? They had the house, Senate, and Presidency in 2017-2018 and the house and senate spent all their engery blocking Trump and explaining why they couldn't do all the things they promised they'd do if they ever had the house, senate, and white house. Then so they wouldn't have to explain anymore why they weren't helping Trump they arranged for the dems to just take the house by having a bunch of safe republicans suddenly retire and hand those seats to dems.
They made 'doing nothing' into a fine art.
