Abortion should be decided state-by-state because democracy is more important

I would sure hope so, but I wouldn’t count on it. Part of the issue, I think, would be that, even if much more than half of Americans would support such a law, they are probably unevenly distributed, and I don’t think that you’d get a majority supporting it in the 3/4 of the states.

Plus, for reasons that are above my pay grade to understand, the Constitutional amendment process seems to be broken – or, at least, not really used any longer.

In the last 50 years, there has only been one Amendment instituted: the 27th. It’s a relatively minor amendment: it delays laws affecting Congressional pay from taking effect until after the next Congressional election (so a Congress cannot technically vote to give themselves a pay raise). And that one, which was implemented in 1992, was first proposed in 1789.
