A Colorado constitutional amendment to make it harder amend the constitution is advancing through the legislature there. It would have to be approved by voters as well. Colorado, unlike many direct democracy states, makes it no harder to qualify a constitutional amendment for the ballot than it is to qualify an initiative statute. The amendment would change that, and also add a distribution requirement, requiring at least 5 percent of the required signatures to come from each of the state's Congressional district.

One caution: Colorado politicians, deluged by ballot measures this year, have expressed unhappiness about the growth of the industry. This measure, by adding requirements, will make that industry stronger. When you have to gather more signatures in more places, those who want to qualify measures will have to rely more on consultants and paid signature gatherers. If you don't like the industry and paid gatherers, you'd be better off drastically reducing the number of signatures required to qualify a measure.
