Debate Ratings: How Many People Watched Trump vs. Harris?
UPDATE: Final numbers are in, and 67.1 million viewers tuned in all tolled. 19.049 million were on ABC News.
PREVIOUSLY (9/11/24, 12:25 p.m.): As expected, the presidential debate between Donald Trump and Kamala Harris on Tuesday (September 10) night was a very widely watched and much-discussed televised event. This was the first face-to-face (and possibly only) meeting of the nominees, following up on the consequential June debate between Trump and then-candidate Joe Biden.
So just how many people tuned in to watch the debate? Complete network viewership numbers are expected to be released later on in the day, but the early overnight figures (which are known to underestimate the total number of audiences, as they are based on broadcast averages for certain time periods and don’t include a full view of the total viewership) are in.
According to analyst Michael Mulvihill, this debate saw a marked increase in viewership over the Trump-Biden debate, as he wrote, “Last night debate earned an overnight rating of 32.8 and a 70 share across eight networks. That’s +28% higher than the Trump-Biden debate earlier this year.”
He went on to add a caveat, saying, “The 28% growth in the overnights ratings implies a national audience of over 65 million, but overnights haven’t been all that reliable as a predictor of the nationals lately, at least in sports, so I’d make that project with low confidence.”
