Kamala Harris and Donald Trump are set to debate in Philadelphia, a crucial event in the 2024 presidential race, as Pennsylvania remains a key battleground state. Polls show the candidates tied at 50% among likely voters, underscoring the tight competition in a state that has historically determined the presidency. Harris aims to rally support from key demographic groups, including college students and Black voters, while Trump seeks to capitalize on economic concerns to weaken Harris's support in suburban areas. Both candidates have made extensive campaign visits, with Harris focusing on issues like abortion rights and Trump's strategy targeting the Biden administration's economic policies. The debate at the National Constitution Center could sway undecided voters and may prove pivotal for both campaigns. With no Democrat winning the presidency without Pennsylvania's support since 1948, the stakes are particularly high for Harris.
