Tabor hasn’t destroyed public funding. The unwillingness of the politician to bring up tax increases for a vote has destroyed public funding. Everyone is so afraid of being labelled as the politician that increased taxes, that our elected officials won’t deal with real issues that require funding.
Colorado’s mess gets more interesting when you take into account rules MikeKStar mentions - that require some spending in some areas, lack of built in flexibility. But mostly it is the will of the government here - they aren’t willing to address the troubles and instead grandstand and complain about how hard it is to do their job with these awefully complicated laws.
I would argue that the ease of placing amendments on the ballots has been a good thing - but our poor leadership has reacted with stupidity: instead of cleaning up the languages, straightening out the rules, they just keep coming up with poorly thoughout stopgap “fixes.” Cf The PERA troubles, and the widespread use of FEES instead of TAXES.
Throughout this all, though - Doug Brouce is a colossal asshole.
