Democrats are seeking a stronger turnout in Philadelphia county in 2020 compared to 2016.

In 2016, Clinton carried Philadelphia county with 584,025 votes, but Trump fared better than Romney, with 108,748 votes and a better margin of 475,277 votes.

Trump’s handling of the pandemic could hurt his chances in Pennsylvania. As of 1 p.m. ET on Saturday, there are 102,602 confirmed coronavirus cases in Pennsylvania, according to the Centers for Disease Control. The state's death toll is at 7,101.

Biden is considered a favorite to win Pennsylvania, a state where he has strong roots. Biden spent the first 10 years of his life in Scranton, an industrial city in the northeastern part of Pennsylvania. His ties to the rust belt help him win back working-class Pennsylvania voters that went to Trump in the 2016 cycle.
