I used to maintain a list of every time the Republicans of Arizona attempted to stop voter initiatives after they’d been successfully passed.
Tried to stop legalizing medical marijuana by suing
Tried to stop the creation of an independent commission for drawing districts by suing. They’ve taken the commission to court on at least five separate occasions and lost (using taxpayer money of course)
Initiative to pay teachers more was dismantled and never took place
That’s just the top of my head. They also famously made voter initiatives harder to pass. But people still vote for them
