After her breakout performance in the first Democratic primary debate, Sen. Kamala Harris got a big surge in both public support and media attention. But with the second debate now over, Harris has lost most of the support that she had gained in the polls and, according to last week’s data from the TV News Archive and Media Cloud, she has also started to slide out of the media spotlight. Harris was mentioned in about 9 percent of all cable news clips that mentioned any Democratic 2020 candidate last week across the three networks we monitor — CNN, Fox News and MSNBC — and she was mentioned in about 19 percent of online news stories that mentioned any candidate. That’s about half as big a share as she had in the previous week and similar to the amount she was being mentioned in the week before the first debate.

Each network’s daily news coverage is chopped up into 15-second clips, and each clip that includes a candidate’s name is counted as one mention. For both cable and online news, our search queries look for an exact match for each candidate’s name, except for Julian Castro, for whom our search query is “Julian Castro” OR “Julián Castro.” Media Cloud searches use two of the database’s publication lists: “top online news” and “digital native” publications.

But Harris was not the only candidate getting less media attention last week. Several other candidates, including Sen. Bernie Sanders, Marianne Williamson, Rep. Tulsi Gabbard and former Rep. John Delaney all slid backwards after post-debate bumps two weeks ago. While most candidates saw some reduction in their share of mentions, Sen. Cory Booker’s media coverage stayed about the same from the previous week. And former Texas Rep. Beto O’Rourke got a lot more media attention following the shooting in his home district where more than 20 people were killed. Speaking from El Paso last week, O’Rourke was vocally critical of President Trump, linking the shooting to Trump’s racist rhetoric. Ultimately though, former Vice President Joe Biden remained the most-mentioned candidate in both cable and online news, as well as the leader in the polls.
