GREELEY — The two Democrats vying for the chance to unseat Republican U.S. Rep. Gabe Evans in Colorado’s 8th Congressional District tried to find ways to attack each other at their first major debate Thursday but ended up agreeing on many major issues. Former state Rep. Shannon Bird of Westminster and state Rep. Manny Rutinel of Commerce City said they want to tax high-income earners and corporations to subsidize things like childcare and healthcare.
