It is an understatement that Increasing fuel taxes is challenging. If there is an opportune time to do it, it's when gas prices are relatively low, when the state decides to cut other taxes, and when there's bipartisan support.
Colorado's roads and highways are in poor repair—the state of transportation was even called a 'quiet crisis' ten years ago. The problems persist, as does the state's lack of funding to fix the problem.
The overwhelming majority of states that increased gas taxes last year were Republican-controlled. In states where the legislature is split, it's more difficult to approve transportation funding legislation. Down-ballot races may prove decisive.
