Kamala Harris needed a win on Tuesday night's US presidential election debate. After an initial honeymoon period as Democratic nominee, her campaign on the ground was running out of steam. Now she and Donald Trump are neck and neck in the polls of key battleground states. All he had to do on Tuesday night was keep his cool and stick the script provided by advisers. Instead, he made a string of rambling statements that ranged from the baseless to the downright absurd. But given how polarised the country now is, the victor of the debate depends on viewers' own political allegiances. So how much of a difference will the performances have in the minds of Americans? Can Harris' debate win do anything to change her trajectory? Irish Times Washington Corresondent, Keith Duggan, reports from Philadelphia where the debate was held.

Presented by Bernice Harrison. Produced by Declan Conlon and Aideen Finnegan.
