Biden will continue to be a milquetoast centrist. He's a very watered down version of Obama and as far as I recall, the 2a was largely safe under Obama.
The far right and the far left will continue to rattle sabers and the fundamentals will remain largely unchanged. There will be small "things" done, and both sides will howl in protest/glee.
Whomever stated that AR's haven't inflated in "panic mode" this time around seems to be largely correct. That part surprises me somewhat, but perhaps, as stated, the market is already saturated.
We shall see.
