Back in 2016 full legalization was actually on the ballot in the general (Prop 205). AZ was the only state of something like 13 total (don’t quote me) with either a recreational or medical legalization measure on their ballots that did not put it through. It failed 48.7-51.3%. AZ’s red politicians really hammered in the donations to oppose it.
Given that younger people then (who are now older) are more likely to support it while also typically voting in smaller proportions than older people, I somewhat confidently predict Prop 207 (this year’s measure) wil pass, looking at the narrowness of the margin from 4 years ago.
Luckily I moved to CO last year so this isn’t a problem for me anymore
