The heavily-anticipated showdown between Vice President Kamala Harris and former President Donald Trump on Tuesday night was seen by 67.135 million viewers, according to Nielsen Media Research.
Hosted by ABC News and simulcast across 17 networks, the Harris/Trump match-up was the most-watched presidential debate of the 2024 election season. It easily topped CNN’s June 27 debate, which attracted 51.3 million viewers
Still, these numbers didn’t match the first debate between Trump and Hilary Clinton in 2016, which 84 million viewers watched. The Harris/Trump debate was down -20% in total viewers compared to that debate.
Meanwhile, the first debate between Trump and President Joe Biden in 2020 drew 73.1 million viewers, which translates to an -8% dip for Harris/Trump in comparison. But the ABC News debate did outdraw the second Biden/Trump match-up, which brought in 62.9 million viewers. That’s a +7% bump in favor of Harris/Trump.
