The story about President Trump’s call to Ukraine dominated the airwaves last week, and along with it came a lot more mentions of former Vice President Joe Biden. Two weeks ago, when the Wall Street Journal broke the news about the whistleblower complaint, cable news increased its coverage of Biden, but not online news outlets. But last week, that changed. As House Speaker Nancy Pelosi announced an impeachment inquiry against Trump and the acting director of national intelligence testified in a public hearing in front of Congress, the share of online news stories that mention Biden also surged. Biden was mentioned in more cable news clips and online news stories last week than all other 2020 Democratic candidates combined, according to data from the TV News Archive and Media Cloud.

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 Julián 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. Percentages are calculated as the number of stories or clips mentioning each candidate divided by the number of stories or clips mentioning any of the 2020 Democratic contenders for that week.

And it seems like the media isn’t only mentioning Biden more — it’s also mentioning everyone else less. Last week, all of the other Democratic candidates who are still running for president were mentioned less than the week prior, and overall the non-Biden candidates were mentioned in more than a third fewer cable news clips and online news stories compared to the week before. All this suggests that the impeachment story could eat up a lot of the media oxygen that would otherwise have been dedicated to the Democratic primary. We’ll be watching the numbers in the coming weeks to see to what extent Biden continues to be wrapped up in the story of Trump’s impeachment inquiry and how much that affects the amount of coverage the other candidates receive.
