(CNN) A major Supreme Court decision has likely transformed election night with a huge break for Democrats -- but it comes with a chilling warning of how the conservative majority might decide future voting disputes. Since more Democrats vote by mail than Republicans, the case is likely to boost Democratic presidential nominee Joe Biden in this crucial swing state. In practical terms, the extended vote counting also means that a tight race in the Keystone State could turn election night into election week. Trump's two confirmed nominees, Brett Kavanaugh and Neil Gorsuch, sided with two other conservative justices to back the Pennsylvania Republicans. It's easy to imagine that had Trump's latest far-right nominee, Amy Coney Barrett, been on the court, the conservative justices would have won 5-4.
