The Democratic Party will have been eviscerated even more at the local level.
That's probably a fair trade, as 8 more years of Democratic executive control will deliver a nearly unanimously liberal federal judiciary from the top-down that will last over a generation.
By 2024, a new Republican president will probably take over - Popular or not, Republicans will then experience their own 1994, arguably worse
(Millennials are the largest generation in history), as the heavily Democratic Millennials will have reached the age where they can begin to dominate midterm elections. Republicans will have lost their more conservative silent generation / older boomers, and will be in a weakened state coalition-wise until they can find a way to appeal to the new generation of young voters.
So the way I see it is, regardless of what happens during this time, it's not going to be a bright future for Republicans during the 2020s - 2030s.
This. The Senate map might even look like this:
So 64 Senate seats? Honestly, even by Atlas predictions, that seems pretty ridiculous given the current state of the Republican party. Republicans haven't had more than a 55 Senate seat majority since the 1920s, and the direction the GOP has been headed for years now will not give it the appeal to achieve that kind of majority.
