I also don’t see a permanent minority party being able to govern long term. That’s the R’s problem and why I mention it. Demographics are decidedly against them. When Texas, GA, NC and AZ flip against them in the next ten years, game over. That’s why the EC and Senate controversies won’t be determinative. The D’s have their own internal issues with moving to far left but there is at least some coalition left there.
A functioning democracy needs viable center left and center right parties to work. I would not be surprised if the R’s go the way of the Whigs in the 1850’s with a new right party coming into play soon. The Whigs in large part were destroyed by know knothingism and slavery expansion. The race and xenophobia issues are also going to undo this party. The current R party has little reason for continued prominence.
