Under Prop. 50, the California map leans Democrats in Issa’s district, complicating his reelection prospects as maps are tested in mid-decade elections.

The new district tilts Democratic, with registered voters favoring Democrats by more than four points and including liberal areas such as Palm Springs, contrasting Issa’s previous GOP-leaning 2024 district.

California Republican Rep. Darrell Issa is retiring from Congress, announcing he will not seek reelection in the newly redrawn 48th District after indicating previously that he would stay.

Issa frames the move as the right time for a new chapter and challenges, closing a 25-year run in Congress and 25 years in business.

Ahead of California’s filing deadline, sources indicate Issa’s bid for reelection is dropping, effectively ending his time in office.

The retirement comes amid a national, ongoing redistricting fight ahead of the November elections, with several states already conducting primaries under new maps.

Redistricting is a broader national battle with states like Texas, North Carolina, Missouri, and Virginia shaping districts for the midterms.

Issa’s retirement unfolds as a crowded field of Democratic challengers, including Ammar Campa-Najjar and Marni von Wilpert, seeks to flip the seat.

Issa ally Desmond says he will fight to improve affordability, safety, and freedom as he runs in the reshaped district.

Democrats had already lined up challengers amid new electoral headwinds in the altered district, intensifying the race.

Prop. 50 redrew Issa’s district to lean Democratic, contributing to the increased difficulty of reelection amid mid-decade redistricting across the country.

Beyond redistricting, Issa has been noted for nominating Donald Trump for the Nobel Peace Prize and other high-profile political actions.
