It’s easier to change Colorado’s Constitution than nearly any other state.
In the late 1880s, railroad barons were the most powerful people in the country- especially in rapidly growing states west of the Mississippi. They exerted a tremendous amount of influence over politicians. In 1910, citizens in Colorado who were frustrated by the power of these special interests decided to allow voters to enact laws directly via the ballot initiative process. Since then, Colorado has in place a hybrid model of state government, combining representative democracy with direct democracy.
