Who won the US presidential debate?

Donald Trump and Kamala Harris met for the first time on the presidential debate stage in Philadelphia last night.

They may have shaken hands, but they did not hit it off. In a fiery 90 minutes, Harris frequently rattled the former president with personal attacks that threw him off message and raised the temperature of this highly-anticipated contest.

Her pointed digs on the size of his rally crowds, his conduct during the Capitol riot, and on the officials who served in his administration who have since become outspoken critics of his campaign repeatedly left Trump on the back foot.
