HARRISBURG, Pa. — The U.S. Supreme Court on Monday let a court-ordered redrawing of congressional districts in Pennsylvania proceed, raising Democratic hopes that a revamped map might yield them several more seats this fall.

Justice Samuel Alito, who handles emergency appeals from Pennsylvania, rejected the request from GOP legislative leaders and voters to put on hold an order from the state Supreme Court intended to produce new congressional districts in the coming two weeks.

The Pennsylvania high court ruled last month that the current map of 18 districts violates the state constitution because it unfairly benefits Republicans.

The decision comes just four days before the Republican-controlled Legislature’s deadline for submitting a replacement map for Democratic Gov. Tom Wolf to consider. So far, there has been a notable lack of bipartisan movement on getting such a deal.

Pennsylvania’s congressional delegation has been 13-5 in favor of Republicans during the three election cycles since the GOP-drawn 2011 map took effect, and experts have said those 13 seats are several more than would have been produced by a nonpartisan map.
