Supreme Court Clears Way for California Voting Map

The Supreme Court on Wednesday cleared the way for California to use a new congressional map designed to help Democrats for the midterm elections. The justices rejected an emergency request by the California Republican Party to override an appeals court and block the map before the November vote. The decision is a victory for Democrats, who had devised the plan after President Trump pushed Republican-led states to redraw their maps to help the G.O.P. pick up seats in the election.

In December, the Supreme Court cleared the way for Texas to use its new congressional voting map for the midterm elections. Texas Republican leaders had asked the court to weigh in after a divided panel of federal judges had temporarily blocked the map, which was designed to help the G.O.P. potentially pick up seats.

In a concurring opinion in the Texas case, Justice Samuel A. Alito Jr. nodded to efforts to gain a partisan advantage by both parties before the midterms, writing that it was “indisputable” that “the impetus for the adoption of the Texas map (like the map subsequently adopted in California) was partisan advantage pure and simple.” Courts have said it is legal to gerrymander based on party politics as opposed to race.

Hours after the state’s voters overwhelmingly approved the plan in November, leaders of the California Republican Party sued. A divided three-judge panel in federal court in Los Angeles upheld the map. A district judge, writing for the majority, said the evidence showed that the state’s new map “was exactly what it was billed as: a political gerrymander designed to flip five Republican-held seats to the Democrats.”

The California Republican Party quickly appealed to the Supreme Court. In a brief to the justices, the challengers argued that “under the guise of partisan line-drawing,” California “expressly used race” in drawing up its map, a “pernicious and unconstitutional” action. Lawyers for the Trump administration weighed in with a brief supporting the state Republican Party. Solicitor General D. John Sauer asserted that the justices should treat California’s map as different from the Texas map because California’s map was “tainted by an unconstitutional racial gerrymander.” Mr. Sauer argued that the state’s new district boundaries had been drawn to bolster Latino voters.

In response to the emergency application, Mr. Newsom and Secretary of State Shirley Weber, both Democrats, denied that the map had been drawn to give an advantage to Latinos. They pointed out that the number of Latino-majority districts in the state remained unchanged under the new map. The state leaders said in their brief that it would be “strange” for California to redistrict to help Latino voters and then adopt a map with the same number of majority-Latino districts.
