Democratic Sen. Dianne Feinstein easily secured the top runoff spot in her re-election race despite a challenge from the Left on Tuesday.

Progressives boosted state Sen. Kevin de Leon’s bid against Feinstein, urging the veteran senator to step aside and make room for the next generation. But Feinstein’s support in California runs deep and de Leon has been unable to overcome his name recognition deficit. She led de Leon, who also advanced to the general election, by more than 30 points.
