John Hickenlooper was around the same age as Roy Cooper when he ran for the Senate in 2020 and unseated Cory Gardner in the CO-SEN race. He had served as Governor of Colorado for two terms prior to being in the Senate.

Hickerlooper unseated Gardner by close to 10% points (9.3% to be exact). That's appropriate considering how much CO as a state has moved to the left since then.
