WASHINGTON—Former Colorado Gov. John Hickenlooper shrugged off a series of campaign stumbles to win the state’s Democratic Senate nomination on June 30, beating a progressive challenger in a race vital to the party’s hopes of regaining Senate control in November.
Hickenlooper’s victory sets up a high-profile Nov. 3 showdown with conservative Republican Sen. Cory Gardner, considered one of the country’s most vulnerable incumbents and a top target for Democrats.
