:Former President Donald Trump scored a clear win at the U.S. Supreme Court on Monday, which unanimously ruled that states don’t have the ability to bar him — or any other federal candidates — from the ballot under a rarely-used constitutional provision that prohibits those who “engaged in insurrection” from holding office. The decision shuts down a push in dozens of states to end Trump’s candidacy through a clause in the 14th Amendment, written to prevent former Confederates from serving in government after the Civil War. But it may open the door to further electoral uncertainty, exposing more state officials to disqualification under the provision and setting up a constitutional showdown should Trump win the election.
