Issue #2 passing proves it...it was an anti-monopoly amendment.
It says that over half of the electorate opposed a monopoly.
Issue 2 passed by a lot less than Issue 3 was rejected by. You had 48% saying they were fine with monopolies but only 36% saying they wanted the pot monopoly.
All 52% who voted against monopolies may have been anti-pot too. It’s up to you to provide evidence otherwise.
