Biden also carried Arizona, Wisconsin and Michigan on his path to the presidency, flipping states that President Donald Trump won in 2016.

Pennsylvania was a must-win state for Trump.

The 77-year-old Biden was born in Scranton, Pennsylvania, and sought to contrast his working-class roots with the affluent Trump’s by casting the race as “Scranton versus Park Avenue.”

Biden’s victory came after more than three days of uncertainty as election officials sorted through a surge of mail-in votes that delayed the processing of some ballots.

Trump is the first incumbent president to lose reelection since Republican George H.W. Bush in 1992.
