Washington — On June 30, incumbent Colorado Democrats faced progressive primary challenges as voters prepared to decide intra-party nominations. Representative Diana DeGette was challenged by Melat Kiros, and Senator John Hickenlooper was challenged by state Senator Julie Gonzales; reporting identified challengers' positions on Israel and immigration enforcement ahead of the primary. Denver-area campaigns intensified mobilization this week, with volunteers and candidates urging turnout on the eve of the vote and the Denver Post noting local campaign events and a 7 p.m. primary deadline. If incumbents are defeated on Tuesday or in subsequent ballot counts, observers say it would highlight a leftward trend within parts of the Democratic Party.
