A federal judge in texas ruled last year that preventing people under indictment from purchasing firearms was unconstitutional based on the Supreme Court’s Bruen decision, just FYI. So I don’t think the situation is as cut and dry as it would have been just a couple years ago.
Congress passed the bill back in the 70s. They’d have to pass another bill to undo it. With corporate lobbying from the auto manufacturers it’s very unlikely. They make bank on SUVs and trucks. Hell, the only model Ford sells that isn’t a truck or SUV is the Mustang.
