From https://www.smithsonianmag.com/history/twelve-failed-constitutional-amendments-that-could-have-reshaped-american-history-180987425/

The United States Constitution had been in effect for little more than a year when Congress first moved to amend it. On September 25, 1789, the legislature sent a dozen proposed amendments to the then-13 states (soon to be 14) for ratification, as the law required. By December 15, 1791, the necessary three-fourths of states had ratified 10 of the 12 amendments, which collectively became known as the Bill of Rights.

Another 17 amendments have been ratified in the 234 years since, for a total of 27. But these measures represent just a tiny fraction of the amendments that have been proposed in Congress over the years—nearly 12,000 to date.

You need to look at it a bit differently: it's not that 38 states are needed to approve amendments, but rather that only 13 states are needed to block them. And Republicans have been very effective at electing politicians at the state level. Republicans have total control of 28 State Legislatures, and also hold the Governor's seat in 23 of them.

So, any amendment that manages to get through Congress (and the filibuster) will have to be approved by a bunch of these State Republicans. So pretty much any policy that that can be considered liberal will be DOA.

In fact, Democrats have more to worry about in the other direction. They only hold 18 State Legislatures, holding the Governor's seat in 16 of them. That is perilously close to the threshold of not being able to block amendments. If Democrats lose just a few more of those safe states, the the next time Republicans hold majorities in the House and Senate, they may be able to force amendments through that the blue states don't like.

The republicans are doing literally everything in their power to protect pedophiles and child sex traffickers. If raping and murdering 12-year old girls isn't too much for them, what makes you believe that republican-led states would agree to anything other than increasing their own power or wealth?

I don't think I should know the US constitution.

I can’t think of a single thing that would garner such support. You could suggest an amendment that convicted child rapists couldn’t hold public office and there would be enough pushback that even that wouldn’t succeed.

A constitutional amendment requires 2/3 of both houses of the legislature, and ratification by the states. Passing a law with a veto-proof majority requires 2/3 of both houses. So I don't think a constitutional amendment is any easier.

It also allows the calling of a Convention to amend the constitution if only 2/3 of states make application for one, without approval of Congress.
