The Supreme Court on Thursday allowed Texas to use a congressional map that will boost President Donald Trump’s effort to keep Republicans in control of Congress, blocking a lower court decision that found the new boundaries were likely unconstitutional because they were drawn based on race.

The decision could have significant consequences for next year’s midterm elections, which will determine control of the House for the final two years of Trump’s presidency. Had Texas been blocked from using its new map, it would have upended Trump’s nationwide push to avoid a Democratic House majority.

The court issued a brief unsigned opinion granting Texas’s request over the objection from the court’s three liberal justices.

In its brief order, the Supreme Court said that a lower court that ruled against the map likely did so in error, in part because it failed to honor “the presumption of legislative good faith by construing ambiguous direct and circumstantial evidence against the legislature.”

...The legal battles over Trump’s mid-decade congressional redistricting strategy will continue to play out in coming weeks. Last week, the Justice Department sued officials in California over new maps meant to give Democrats in the Golden State an edge next year. A court is set to hear arguments in that case next month.
