I think they're going to have to find a way to interpret the 2nd to allow firearms ONLY if you take some sort of loyalty oath. 'They' want MAGA/GOP loyalists to be armed, just not those pesky Democrats and left-leaning Independents. And despite what one may think, there is quite a bit of gun ownership in the Left. They just don't bleat about it.
It'll be interesting since individuals states and, in some places, counties set their own laws regarding possession of firearms (not violating federal law).
So I think the 2nd will remain, it'll just be interpreted differently. And not in a good way.
