Slate of changes to Colorado’s amendment process filed

There’s one thing Democrats and Republicans always seem to agree on in Colorado – that it’s too easy for citizens to change the state constitution.

A bipartisan civic group renewed the effort Tuesday by filing a slate of ballot measures to make it harder.

The measures would require ballot petition signatures to be collected across the state. They would also raise the threshold for changing the constitution from a simple voter majority to 55 percent.

Voters would have to approve the changes.

The civic group has been touring the state to gauge support for constitutional changes. The group has not called out any constitutional amendments it opposes. Marijuana legalization and spending restrictions known as the Taxpayers’ Bill of Rights are among the amendments placed in Colorado’s constitution by voters.
