Colorado voters had a chance to increase taxes drastically. Amendment 66, which would have made Colorado’s taxes very progressive (with far higher taxes impacting most citizens), was defeated. With about half the votes cast, the no’s were leading by 66% to 34%.
The initiative was sponsored the the teachers union and was strongly supported by Democrats including Colorado Governor John Hickenlooper. The supporters outspent those opposed; however, it appears not to have mattered with Colorado voters.
