From the link:
This will be a difficult program to enact for the Biden regime. In 2020 a record number of Americans bought guns. According to the National Shooting Sports Foundation 8.4 million people bought a gun for the first time in 2020.
Not saying he can’t get it done, but it’s far from a certainty. Obama had the House and Senate for two years and couldn’t get it.
Honestly, I doubt the majority of the problem will come from those 8.4MM new gun owners.
The problem will mostly come from military veterans and long-time gun owners aged 45-70 who do not have young children and would rather fight than comply.
I think I know a few of those guys.
