The Denver Post: Lawmakers from both parties have been talking about it for months, and now they’ve finally introduced legislation that would ask voters to make it harder to change Colorado’s constitution. Voters in 2008 shot down Referendum O, a similar referred measure from lawmakers that would have made it harder to amend the constitution.

The Longmont Times-Call: Senate President Brandon Shaffer has formally introduced a proposed constitutional amendment that would make it harder to make most other changes to Colorado’s Constitution in the future. The Longmont Democrat and other critics of current procedures for revising the constitution have objected that it’s now too easy to petition proposed amendments onto the ballot. Those critics also have charged that the current voter-approval bar for passing such constitutional changes is too low.
