Trump made an aggressive play for pivotal Pennsylvania, focusing largely on his white, working-class base. His first of four scheduled stops in Pennsylvania was in a small-town Bucks County on the eastern edge of the state. Repeating what has become a consistent part of his closing message, Trump raised concerns about election fraud, pointing specifically at Philadelphia, a city whose large African American population is key to Biden's fate in the state. The president also railed against a recent Supreme Court ruling that will allow Pennsylvania to count mail ballots received as many as three days after polls close. The extra time, Trump alleged without evidence, would allow for fraud and potentially deny him a win in the state. "That was a very disappointing opinion, but I've had many disappointing opinions from the Supreme Court,” Trump had said.
