LOS ANGELES – Six weeks after winning an overwhelming victory among the top voters in California, Senator Dianne Feinstein suffered an embarrassing backstroke Saturday night when the state democratic party officially approved his rival for elections in November.
Kevin de León, the Democratic leader of California's state council, won the support of the party leadership despite an intervention by Ms Feinstein to persuade the party not to offer an approval.
The voice of Mr. de Leon reflected the emergence of younger liberal activists in California Democratic leadership, some of whom consider Ms Feinstein to be moderate compared to the intensively progressive voices that come up through party leaders. These activists tend to be younger and more inclined than the state at large.
In a tweet following the approval, Mr. de Leon wrote: "Accepting so many leaders and activists from the @ CA_Dem party is not just a glory and privilege. Today's vote is a cleareyed rejection of politics as usual in Washington, DC "
Mr.. The leon victory was the latest of several triumphs for Liberals in Democratic Primary elections this year. Mostly, Alexandria Ocasio-Cortez, a New York community organizer, made a fantastic rebellion over representative Joseph Crowley, a leader of the Democratic Party and 19-year-old commander in his bid for renomination last month. Ms Ocasio-Cortez is the most prominent of several members of the Democratic Socialists in America who have won prime ministers for state and local offices this year.
Two other progressive, Jared Polis of Colorado and Ben Jealous of Maryland, also challenge challengers last month for the democratic nomination of governors in those states.
Ms. Feinstein defeated Mr De León in California Senate last month and received 44.2 percent of the vote to 11.5 percent. She carries all state counties.
Jeff Millman, Ms. Feinstein's campaign manager, expressed confidence on Saturday night that "a large majority of California Democrats" will vote for re-election in the fall. In an email, he noted that 217 Democratic Party delegates had voted to support Mr de León, while Ms Feinstein received more than two million votes in California.
