US Supreme Court rejects challenge to California redistricting map | Elections News

The United States Supreme Court has ruled in favour of a California redistricting measure meant to net the Democratic Party more congressional seats, rejecting a challenge from the state Republican Party.

There was no dissent in Wednesday’s decision, and the conservative-majority court did not offer any explanation for its decision.

Instead, its order was comprised of a single sentence, stating that the Republican application “is denied”.

Previously, in December, the Supreme Court had allowed a similar redistricting measure, designed to benefit Republicans in Texas, to move forward.

Democratic officials in California have applauded Wednesday’s decision as fair, given that Republican President Donald Trump has led a nationwide push to redraw congressional districts in his party’s favour.

“Donald Trump said he was ‘entitled’ to five more Congressional seats in Texas,” California Governor Gavin Newsom said in a written statement.

“He started this redistricting war. He lost, and he’ll lose again in November.”

California’s Attorney General Rob Bonta echoed Newsom’s remarks, blaming Trump for launching a kind of redistricting arms race that threatened to disenfranchise Democratic voters.

“The US Supreme Court’s decision is good news not only for Californians, but for our democracy,” Bonta said in the statement.

Fighting for control of the House

The Supreme Court’s decision marks a win for Democratic efforts to counter the Trump-led redistricting efforts, which began last year in Texas.

In June last year, reports emerged that Trump had personally called Texas state politicians to redraw their congressional districts to give Republicans a greater advantage in Democrat-held areas.

Each congressional district elects one person to the US House of Representatives, which has a narrow Republican majority. Out of 435 seats, 218 are held by Republicans, and 214 by Democrats.

Texas, a Republican stronghold, proceeded to approve a newly revamped congressional map in August, overcoming a walkout by Democratic legislators.

That, in turn, prompted Newsom to launch a ballot initiative in California to counteract the Texas effort.

Just as the new Texas congressional map was designed to increase Republican seats by five, the California ballot initiative, known as Proposition 50, was also positioned to increase Democratic representation by five.

Voters in California passed the initiative overwhelmingly in a November special election, temporarily suspending the work of an independent redistricting commission that had previously drawn the state’s congressional maps.

Newsom, a possible 2028 presidential contender, framed Proposition 50 as a means of fighting “fire with fire”.

The new map approved under Proposition 50, however, will only be in place through the 2030 election, and Newsom has pledged to repeal it, should Republicans in Texas do the same with their new map.

Debate over gerrymandering

The push to redistrict for partisan gain — a process known as gerrymandering — has long faced bipartisan pushback as an attack on democratic values.

Normally, redistricting happens every 10 years, after a new census is taken, to reflect population changes.

But this mid-decade redistricting battle comes before the pivotal 2026 midterm elections, which are slated to be a referendum on Trump’s second term as president. Trump has already expressed fear that he might be impeached, should Congress switch to Democratic control.

Partisan gerrymandering is not necessarily illegal, unless it purposefully disenfranchises voters on the basis of their race. That, in turn, is seen as a violation of the Constitution and the Voting Rights Act, an important piece of civil rights legislation from 1965.

In response to the passage of Proposition 50, Republicans in California sued Newsom and other state officials in an effort to overturn the new congressional map.

They argued the new map was created “specifically to favor Hispanic voters” and would dilute the representation of Republican voters in the state.

The Trump administration joined the lawsuit on November 13, backing the state Republicans.

But Bonta, the California attorney general, argued the redistricting process was legal. In court filings, he also maintained that Trump’s backing of the lawsuit was driven by self-interest.

“The obvious reason that the Republican Party is a plaintiff here, and the reason that the current federal administration intervened to challenge California’s new map while supporting Texas’s defense of its new map, is that Republicans want to retain their House majority for the remainder of President Trump’s term,” his court filing said.

Bonto also called on the Supreme Court not to “step into the political fray, granting one political party a sizeable advantage” by overturning Proposition 50.

The victory for California Democrats on Wednesday comes as redistricting fights continue across the country.

Already, states like North Carolina, Ohio and Missouri have adopted new congressional maps to favour Republicans. There has been pushback, though.

In December, Indiana’s Republican-led legislature voted down a partisan redistricting measure, despite pressure from Trump to pass it.
