Monmouth University: “Among all registered voters in Pennsylvania, the race for president stands at 54% for Biden and 42% for Trump. Another 1% support Libertarian Jo Jorgensen and 2% are undecided. Biden maintains a sizable lead when likely voter models are applied. A model based on a somewhat higher level of turnout than 2016 puts the race at 54% for Biden and 43% for Trump, while one reflecting lower turnout has it at 53% for Biden and 45% for Trump.”
In September, Monmouth had Pennsylvania at Biden 49 – Trump 45.
