A constitutional amendment will never occur again, because it is an incredibly high bar to overcome even when the legislative process in the country isn't as dysfunctional.

One party would need a super majority in both houses of Congress, where the bar is 2/3 but you're probably going to need at least ten more than that to prevent the amendment from being scrapped by a contingent of Joe Liebermans.

Then that same party will need a majority in the state legislatures of 38 states to ratify the amendment.

It's just not going to happen.
