More signs of a generational shift among Democrats showed in Colorado's June 30 primary. In a congressional race for the district covering Denver, longtime Rep. Diana DeGette, 68, lost to political newcomer Melat Kiros, 29, who identifies as a democratic socialist. And in a key swing congressional district, state Rep. Manny Rutinel, a progressive, beat a more moderate opponent to win the Democratic nomination. But on the state level, U.S. Sen. John Hickenlooper held off a far-left challenger.
