The Keystone State's 20 electoral votes are tied for fifth-most and Pennsylvania was one of three traditionally blue states that propelled Trump to victory in 2016. Trump, in fact, was the first Republican presidential candidate to win Pennsylvania since George H.W. Bush in 1988.

But Trump's margin of victory over Hillary Clinton was razor-thin. More than six million votes were cast in Pennsylvania and Trump won by 44,000 - or less than one percent. Even a minuscule voter shift could tip the state to Biden.

A Monmouth University poll released last week has Democratic presidential nominee Joe Biden up over Trump by a 54 percent to 42 percent margin That's a significant jump over last month's Monmouth survey that had Biden leading by just four percentage points in the Keystone State with a 49-45 percent edge.
