Hello, all. Today, I am going to look at a history of contentious primaries for Colorado Senate seats, the candidates involved, and the elections that resulted from them. I chose this topic ahead of the 2020 Senate Primary here in Colorado this June, which will pit former Speaker of the Colorado House of Representatives Andrew Romanoff against former Governor of Colorado and Presidential candidate John Hickenlooper. It has all the trappings of a close race with lots of money thrown in, and who knows what could happen after Romanoff had a surprise runaway victory in the caucuses earlier this month.
