With eight days to go until the U.S. election, President Donald Trump addressed boisterous rallies in Pennsylvania on Monday, while Democrat Joe Biden made a low-key appearance in the state considered crucial to the chances of victory for both men. "We win Pennsylvania, we win the whole ballgame," Trump told a rally in Martinsburg, his third and final event of the day, as he predicted a win in the state despite trailing Biden in most opinion polls. Biden made a small-scale appearance in the city of Chester, near Philadelphia, meeting with about a dozen campaign volunteers and speaking with reporters.
