First you get 290 votes in the House, the body that needed 15 tries to get a simple 218 vote majority to decide who their own leader was.
THEN you need 67 votes in the Senate, the body that can’t muster 60 votes to over-ride filibuster after filibuster.
If by some miracle, you get those votes, then you need ratification by 38 states, from a country that broke 25 states for Biden and 25 states for Trump in the last election.
Here’s the map, find 13 red states that will vote to give up their guns. Keep in mind, of the 25 Biden states, only 19 of them have Democratic statehouses, so you’ll likely lose six of them as well and for every blue state you lose, you need 1 more red state.
So, yes, given the current state of American politics, the Amendment will never change. Same as if, say, you wanted an Amendment protecting abortion, or establishing the size and term limits of the Supreme Court.
