DENVER (CBS4)– The preliminary map to redraw Colorado’s state legislative districts is already re-shaping next year’s election. The map pits 20 incumbent state lawmakers against each other, including State Representatives Julie McCluskie and Dylan Roberts.

Roberts announced Tuesday that he is running for a state Senate seat, previously held by term-limited Kerry Donavan, instead. Roberts is maybe best known for his efforts to lower the cost of health care in Colorado. He was the lead sponsor of a law to create the Colorado Health Insurance Option, which aims to lower premiums by 15 percent, as well as a law that caps the price of insulin.
