After Prop. 50, San Diego may lose its only Republican in Congress as Democrats target Issa

"Eleven Democrats are vying to unseat Rep. Darrell Issa, a San Diego Republican, after California's redistricting measure turned his reliably red district into a slightly blue one that will be a key swing race in next year's midterm elections. Rep. Mike Levin, a San Clemente Democrat, can breathe easier, as Proposition 50 carves out new boundaries that make his swing district more safely Democratic."

"The new voting map reflects California's bid to offset Texas' effort to secure control of the House by adding five Republican seats in November. California voters approved the redistricting plan proposed in Proposition 50 by nearly 20 points in a special election this month. Both redistricting efforts are embroiled in litigation. On Tuesday a federal court blocked Texas from using its new maps, finding that they would harm Black and Latino voters in that state."

Proposition 50 redrew California congressional boundaries, shifting the 48th District's voter registration from a 12-point Republican advantage to a 4-point Democratic lead. The change makes the district a key swing seat and has attracted a large Democratic field, including Ammar Campa-Najjar and San Diego City Council Member Marni von Wilpert. The redistricting moved the district west and north, removing conservative East County backcountry and adding North County areas. The plan benefitted Rep. Mike Levin by making his district more safely Democratic. Both California's and Texas' new maps face litigation, with federal courts and the Justice Department challenging their impacts on voters.
