ATLANTA (AP) — Both President Joe Biden and his Republican rival, Donald Trump, hope to jolt a campaign that many voters are just beginning to watch. Thursday’s debate in Atlanta offers unparalleled opportunities for both candidates to try to shape the political narrative. For Biden, the debate gives him the chance to reassure voters that, at 81, he’s capable of guiding the U.S. through a range of challenges. The 78-year-old Trump, meanwhile, could use the moment to try to move past his recent felony conviction in New York. Their performances have the potential to alter the trajectory of the election.
