Former GOP Rep. Devin Nunes and five other California House members have announced they are calling it quits, adding to an incumbent exodus from Capitol Hill in the run-up to the midterms this year.

Experts said the departures will have little effect on the makeup of the state’s delegation to the House after November. Still, the multiple exits, including several longtime House members, could open the door for candidates of underrepresented communities to seek office.

“It doesn’t look like it will shift anything major for either party in California,” said Michael Li, a senior counsel for the Brennan Center for Justice’s Democracy program. “But without some strong incumbents that have the advantages of name recognition, it will be easier for candidates of certain communities to win a district if it’s open.”

Forty-two House members representing 23 states have announced their exits from Congress in recent months as they either retire or seek another office. That number doesn’t include one currently vacant seat.
