James Carville slammed Democratic National Committee vice chair David Hogg on Wednesday after the activist backed plans to oust incumbent Democrats in solid blue districts.

“Well, it’s the most insane thing,” said Carville, a longtime Democratic strategist, in an interview with CNN’s Jake Tapper.

Hogg — a school shooting survivor who has since become the first Gen Z’er elected as a DNC vice chair — predicted he’d get pushback as Leaders We Deserve, an organization he leads, announced a $20 million effort to elect younger Democratic primary challengers in traditionally safe, blue districts next year.

“This is going to anger a lot of people,” said Hogg, who predicted a “smear campaign” against him in an interview with The New York Times.

He stressed that the organization isn’t telling older Democrats that they “need to go,” rather, he hopes to make way for a new generation that’s “most acutely impacted by a lot of the issues that we are legislating on — that are actually going to live to see the consequences of this.”

Hogg noted that age isn’t the only factor in the organization’s plan, adding that he thinks the likes of Rep. Jan Schakowsky (D-Ill.) and former House Speaker Nancy Pelosi (D-Calif.) — who are age 80 and 85, respectively— should be reelected.

Hogg told MSNBC on Wednesday that there are “great older people” leading the fight against Trump but the party’s lack of popularity and its lost voting shares with most demographics make for a “huge problem.”

Carville, a lead strategist for Bill Clinton’s 1992 presidential campaign, sounded off on Hogg’s plan during his CNN appearance.

“Does he really think the problem that we’re facing in the United States today is because we got 65-year-old Democrats in office? Why don’t you take on a Republican? That’s your job,” Carville said.

Carville went on to critique himself, commenting that perhaps he’s “old fashioned, antiquated” and “not part of the hip generation.”

“But I actually thought our job was to beat Republicans. How quaint, how quaint of me,” he said before quipping. “But I don’t think I’m going to change.”
