Adam Liptak for the NYT:

The Supreme Court on Tuesday refused a long-shot request from Pennsylvania Republicans to overturn Joseph R. Biden Jr.’s victory in the state, delivering an unmistakable rebuke to President Trump in the forum on which he had pinned his hopes.

The Supreme Court’s order was all of one sentence, and there were no noted dissents. But it was nonetheless a major setback for Mr. Trump and his allies, who have compiled an essentially unbroken losing streak in courts around the nation. They failed to attract even a whisper of dissent in the court’s first ruling on a challenge to the outcome of the election.

The court now has three justices appointed by Mr. Trump, including Justice Amy Coney Barrett, whose rushed confirmation in October was in large part propelled by the hope that she would vote with the president in election disputes. But there was no indication that she or the other Trump appointees were inclined to embrace last-minute arguments based on legal theories that election law scholars said ranged from the merely frivolous to the truly outlandish.

Mr. Trump and his Republican allies have lost about 50 challenges to the presidential election in the past five weeks, as judges in at least eight states have repeatedly rejected a litany of unproven claims — that mail-in ballots were improperly sent out, that absentee ballots were counted wrongly, that poll observers were not given proper access to the vote count and that foreign powers hacked into and manipulated voting machines.

Mr. Trump has not come close — even once — to overturning the results of a single state’s election, let alone the results in at least three states that he would need to take a victory from Mr. Biden. And around the country, judges have started to express their frustration with his attempts to have the courts substitute their will for those of voters.
