DENVER (AP) - State Senate President Brandon Shaffer says he's tired of Colorado being a test lab for proposed constitutional amendments pushed by special interest groups around the country, and he wants to raise the bar.
Colorado's constitution has been amended over 50 times in the last 30 years. The U.S. Constitution has been amended 27 times.
In 2010, voters only approved one of seven proposed amendments on the ballot - a measure allowing state government to meet outside Denver in the event of a disaster. In 2008, only four of 14 amendments passed.
Shaffer wants to increase the number of votes needed to pass an amendment from a simple majority to as high as 60 percent. He also wants to require that petition signatures be gathered in each of the state's seven congressional districts.
