Something that must be kept in mind that is profoundly different with Biden's administration and most any others within the past few decades is that he and we know his is/was designed as a one term administration. Why is that important to know? Well, since he is resigned to accept this one term he doesn't have to be the least concerned about burning any bi-partisan bridges during this 4 years. He can, and will, run roughshod over anyone who contests him and worse than that he'll be repaying those who put him in the office regardless of how it sets with the voters...... the opposition voters anyway.
He can do just about anything he wants to do or anything he's put up to doing for the other side. Witness the fact he's already signed something near 45-50 EO's in less than a month. Now he has claimed on several occasions that "he's not making law, he's only ending bad policy". That's pretty hard to swallow unless you're in the market to buy a certain bridge. For at least the next four years they're as good as 'making law'. Yes they can all be rescinded in the next four, but only if a conservative is elected. If another liberal is elected for a two term administration that'll be twelve years then they're as good as law. Just consider the damage to the country just from the lax immigration policies he's put into place already.
Unlike most other POTUS's of recent years who all thought they would run for a second term and had to be very careful during the first term, he's totally content to step aside in 4 years and make room for (most likely) Kamala.
This in itself makes it very likely he will at least try to implement some amount of gun control legislation during this first term. And if he finds he can't get it done through legislation, he'll throw out every last rule in the senate, some of which he's contemplating already, pack the circuit courts and the SCOTUS, and do it by way of liberal 'legislate from the bench' judges. And as a very last resort at some point he'll use the EO's to the nth degree.
We must all stay vigilant and use every legal means available to resist him and any gun control regulations he or his appointed representatives might try to force on us.
