Well, there is a lot of talk about changing the mandatory minimum sentencing that came about due to the WOD, so at least there is headway being made on that stupid law - some more reasonable discussion is being had about that.
Can I point to something other than prohibition directly? Not off the top of my head, but I am sure there are some good examples - perhaps the stamp act...
I’ll see what I can muster, but the person who first said what I echoed originally about getting a bad law repealed by fully implementing it was pretty erudite to begin with. It’s too bad he’s not alive to instruct us today! His quote was “The best way to get a bad law repealed is to enforce it strictly”. - Abraham Lincoln
The Assault Weapons ban. Not technically a repeal, but effectively one.
