The Democrats see gun control as a way to harm Republicans. Most gun owners are Republicans. The reason most gun owners are Republicans is that the Democrats have been attacking them--us--since at lest 1960.
I don't see any restrictive legislation this time. In 1994 the so-called Assault Weapon Ban did not confiscate or prevent the purchase of any AR15. All it did is require new AR15s to not have a flash suppressor or a bayonet stub. And it expired in 10 years. There were 500,000 AR15s in private hands then. There are an estimated 20,000,000 now. The dems don't want to lose votes.
