Trump cheered a decision striking down Pennsylvania pandemic restrictions.

President Trump enthusiastically hailed a federal judge’s decision striking down coronavirus restrictions in Pennsylvania that had been imposed by the state’s Democratic governor, Tom Wolf.

Within an hour of the ruling being handed down on Monday, the president had retweeted no fewer than a dozen celebratory posts, including one that read “PENNSYLVANIA GOVERNOR TOM WOLF AN YOUR STUPID WIFE …..YOUR NOT GOING TO MURDER US !!! TRUMP 2020 … WE LOVE PENNSYLVANIA.”

The decision, which Pennsylvania officials intend to appeal, is at the center of the political dogfight in a once-reliable blue state Mr. Trump won in 2016. To repeat his victory, he must spike turnout in rural counties, where his culture-war message on masks and state restrictions has resonated with conservative voters.

Mr. Wolf has called the challenge to the rules “cowardly.” Pennsylvania has recorded more than 150,000 virus cases and nearly 8,000 deaths, and cases have been rising in recent weeks as students have returned to college campuses.
