Ah, that's because the majority of the changes are in Colorado Revised Statues, not the constitution. I hadn't realized that a constitutional amendment could change law. Sure, it can force changes in law, but the other was new to me. Of course, the ballot title does start "Shall there be amendments to the Colorado constitution and the Colorado revised statutes ...", so I suppose both could be amended at the same time. I wonder if editing two things at once violates the single ballot rule?
The real meat is in the CRS, 1-45-103.7 (9)(a).
The voters instruct the Colorado congressional delegation to propose and support, and the Colorado state legislature to ratify, an amendment to the United States Constitution that allows Congress and the states to limit campaign contributions and spending, to ensure that all citizens, regardless of wealth, can express their views to one another and their government on a level playing field.I suspect that, like the US Congress, no law can force a future Colorado legislature to an action, so the whole effort means about nothing.
