Immigration reform is going to require an act of Congress. It's worth asking what Biden would be willing to compromise and what sort of actual reform we'd actually see after it's been butchered to hell. Much like the ACA.
Rolling back Trump stuff won't require an act of Congress. And restoring dreamers won't either, though it'd be much better if it was enshrined in law.
Speaking of which, for all the bluster of "just expand the ACA/restore what's taken away" we forget that the Supreme Court with a conservative majority has agreed to hear arguments on whether or not the law was constitutional. It's entirely possible that regardless of whatever action Biden would take it's not going to matter in the long run because the ACA will be struck down in its entirety and we're back to square one all over again with nothing but Biden's promise of a vague public option that he consistently compares to Medicare, a social program he's consistently throughout his 40 years in Washington has advocated for budget cuts or freezes. So I can't say there's much faith from me at least that he'd do anything of any lasting effect on that issue short of somehow the Supreme Court rules in favor of the ACA which frankly Ian highly unlikely.
The argument for the ACA being unconstitutional is that there's no longer a tax which is why it was originally ruled constitutional. Restore the tax and the case no longer exists.
Also, if you think a democratic Senate and House would vote for medicare and social security cuts that would murder them in their home seats... Well, it won't happen. On top of that, at absolute minimum we'd see Pelosi's prescription drug bill put up which would
drastically reduce prescription drug prices.
Assuming we get the Senate and House. In case where we don't, pretty much everything is doomed no matter the President anyway.
