Yes. It's very simple.
If you can't win a simple majority election, you most certainly cannot get a constitutional amendment through.
That's it.
Now if you can put together a consistent, preferably 2/3, majority in Congress for your position for several elections in a row, and elect sizeable conservative majorities in 3/4 of the state legislatures, then it might make sense to talk about an amendment.
Otherwise, it's like somebody who can't run a mile without collapsing talking about the marathon they're going to run next week.
Might be an entertaining fantasy, and I hope you enjoy it, but it has no basis in reality.
Thanks for the death wish, pal.
