California's 48th congressional district, redrawn under Proposition 50 to incorporate more Democratic-leaning suburbs in San Diego and Riverside counties, now carries a modest partisan advantage for Democrats in the November general election. The retirement of longtime Republican incumbent Darrell Issa opened the seat, allowing San Diego County Supervisor Jim Desmond to consolidate GOP support and advance from the June 2 primary alongside Democrat Marni von Wilpert. A crowded Democratic primary field split the vote, but the district's updated voter registration and historical performance under the new lines underpin the strong trader consensus favoring the Democratic nominee over the Republican challenger.
