Five rural counties in northeastern Colorado voted last week to secede from Colorado and form their own state. The vote was symbolic — to actually form a new state, Colorado's legislature would have to approve it, as would the U.S. Congress — but residents in what would be North Colorado believe they are underrepresented and ignored by Denver.
