Donald Trump and Kamala Harris met on stage for their first, and likely only, debate of the campaign Tuesday night, just a week before early voting kicks off in Pennsylvania, one of the most critical battleground states of the election.

Over an hour and a half Harris needled Trump on everything from crowd sizes to getting “fired” by the American people.

With each jab the former president seemed to become more enraged, his anger distracting him from his own talking points and allowing Harris to set the agenda.

Headlines across the country declared a clear victory for Harris and Trump now says that he will not debate her again. 

But how much will all this matter at the polls? The New Yorker’s Susan Glasser joins Diane to help answer that question.
