Politics is the art of the possible.
That's it in a nutshell. I expect by 2024 Trump, Biden, McConnell, Pelosi et al
will be aging out of the system, fresh(er) faces and fresher policies will slowly begin to break up this logjam of an old farts convention.
More things will become possible in the upcoming decade. Many more things.
Some good things, some bad things, time will tell.
