Its bs just like gun control polls and Affirmative action polls, those issues are extremely "popular" according to polls but not so popular at the ballot measures.
Ballot Measures would weight more heavily toward older people, which Marijuana is less popular with.
Even then, most Marijuana ballot measures pass in the high fifties to low sixties. Michigan's passed with about 56% in support. If it were possible to include all the young people who didn't vote it'd definitely get into the 60% range, and Michigan isn't even a state where it'd be most popular.
I'd find 67% supporting it would be pretty accurate.
Weed failed in 2016 in Az with the same popularity as the 2016 election except the younger latino districts rejected it but I think az6th a white suburban district accepted it. Its really not that popular even if this was 2016.
That's grasping for straws - the AZ ballot was the ONLY one that failed that year out of nine different states.
Even then, it failed 51.3% to 48.7%, hardly game changing. Also AZ as a state skews older than the nation, and a lot has changed since 2016.
Legalized recreational weed passed in 4 states
Cali was 57 43 and younger hispanic districts often rejected it while the beach districts in Orange accepted it. 15 points right of the state
Mass was also like plus 30 clinton but only plus 7 weed. Nevada was plus 2 clinton and plus 9 weed so it was left of the state. And even if the population overall vastly supports it,politicians are only held to the voters standard.. I am pretty sure weed is a majority issue but not a supermajority yet.
Michigan was around plus 10 whitner on election day and only about plus 15 weed. So it is a reasonably popular issue but not super.
