An anti-Biden ad would be so easy, and I wish the NRA wasn't asleep at the wheel.
All they have to do is show old footage of WWII and Korean war soldiers carrying M1 Carbines. Show the Korean War monument. Show an older veteran teaching his kid how to target shoot with that classic wooden-stocked rifle...or show one on the mantlepiece in someone's study, in warm light, with old photographs behind it. Ask how much of a "threat" it is.
And then show an angry Biden, and zoom in to the bit of HR 1022 that shows that it would be banned. Then show the old WWII and Korean photos again.
It is on the list.
