Well I have been out of the country for a while so I missed when Colorado passed a amendment to their state constitution to end involuntary servitude
Nebraska, Utah, Alabama, Oregon, Tennessee and Vermont have all changed their constitutions
California is close, and we have ~25 of the votes left to count
Just this election, Nevada passed Prop3 changing theirs, did hear about it?
Unfortunately, like high-speed trains, this runs up against the limits of our democracy
