Vice President Kamala Harris and former President Donald Trump face off Tuesday night for their first and possibly only debate before Election Day. The state of the race as they meet in Philadelphia is starkly different than it was just more than two months ago, when Trump debated President Joe Biden in a performance that accelerated calls for Biden to leave the race. Since then, Biden ended his campaign and endorsed Harris, Trump survived an assassination attempt, and both tickets named running mates and made their cases to voters at their national party conventions.
