EPA has been toying with banning lead bullets for a long time.
Product liability laws were used by the left as a method of scaring firearm manufacturers.
Many on the left have wanted the CDC to take up firearms and gun violence as a medical issue to be regulated as such.
You could see federal regulations declaring all kinds of federal facilities or things purchased with federal money to be declared gun free zones, like parks, interstate highways, and a host of things. Post Offices, federal buildings are still gun free zones, even if National Parks now allow concealed carry permit holders to concealed carry (outside of federal park buildings).
In short there is probably going to be a long of things that the big Zero is going to be implementing that will make those who believe in the 2nd Amendment mad.
Still the Constitution has a set of Checks and Balances and it has a Bill of Rights. I lived through the first Assault Weapons Ban and 8 years of Bill Clinton, I can live through the Big Zero who is going to make Jimmy Carter look like a successful president.
I remember when Clinton signed an order on his way out to require every water treatment center to raise their arsenic standards. It would have cost local governments billions.
You are correct in that Obastard will be limited in what he can do. Whatever it is, it will still have to be within the law and the Constitution or the EO will be rapidly overturned. As much as Obastard hates to admit it, he can’t simply create a law declaring the AR-15 to be a Class 3 weapon and force everyone to register them as such.
What good is the constitution if there is no one to defend it? Look what Roberts did with the supreme court decisions.. And the republicans in congress are nothing but wimps. They can’t even stand up to Obama over a simple budget. There may be a few hold out judges across the country but Obama has the key people in control that will side with him. And those that do not follow his command, he uses the media or activist groups to destroy them.
