A wide expansion of mail-in voting in Pennsylvania survived a legal challenge on today before the state Supreme Court in a case brought by some of the same Republican state representatives who voted for the legislation nearly three years ago. Millions of state voters have chosen to cast ballots by mail in recent elections, although Democrats have used it in far greater numbers and the law fell out of favor with Republicans as former President Donald Trump attacked it during his losing 2020 reelection campaign. The 5-2 ruling, with the two Republican justices both voting no, means expanded vote-by-mail will almost certainly be in place for marquee races in November for governor and U.S. Senate.
