Bronin, 47, attacked John Larson as an establishment Democrat.

“Congressman Larson has been in office for 28 years,” Bronin said on NBC this week as he argued it’s time for a change.

WATCH:

Voters have made clear they’re sick of establishment politicians who think seniority is the be-all and end-all of public service.

Bronin pounced on John Larson over his age and health issues.

Last February, Larson froze up mid-sentence during a speech on the House floor.

He never fully recovered from the medical episode. Bronin repeatedly attacked Larson over his age and health issues.
