Data: NewsWhip; Chart: Chris Canipe/Axios

Bernie Sanders captured more online conversation than any other candidate last week following his proposal to wipe out $1.6 trillion in student debt, according to data from NewsWhip exclusively provided to Axios as part of a project that will regularly update throughout the 2020 campaign.

Why it matters: It shows that the topics that got outsized media attention weren't the ones that animated people the most. Articles about Sanders generated 5.7 million interactions on Facebook and Twitter over the last week, 64% more than those about Biden, the candidate with the second-most interactions.

Reality check: Kamala Harris generated more interactions on debate day and the day after than any other candidate — but those numbers were still 16% shy of Bernie's for the Monday of the college debt policy release and the next day.

  • Biden had the second-highest numbers for a debate day, although many of those mentions were from stories about Harris' pointed criticism of his history with racial issues.

Between the lines: These numbers put on display the gulf between the coverage that is most visible with the coverage that generates the most intense interest. Coverage that emerges from a high-profile television event can be high-volume, low-engagement, while policy proposals that can be invisible until surfacing in social feeds can have an extraordinary velocity.

By the numbers: Forbes' story of Sanders' college debt proposal generated more than 769k interactions — almost four times more than the biggest story for any other candidate.

  • 5,031 stories were published about Bernie last week — 1,600 fewer than Harris and 3,800 fewer than Biden.
  • But the engagement for Bernie was much more intense: His stories got 1,129 interactions per article, compared to 393 for Biden and 514 for Harris.

Yes, but: While post-debate polling showed a marked uptick for Harris, Sanders' support was flat. It is an indication that while Sanders has an animated and active base, his support may be saturated.

  • His strong name recognition from the 2016 campaign means that he carried over much of that support, but may struggle to expand beyond that group.

Astronaut Mark Kelly (D) was sworn in to the U.S. Senate on Wednesday after defeating incumbent Sen. Martha McSally (R-Ariz.) last month for the seat once held by the late Sen. John McCain.

Why it matters: Kelly's swearing-in by Vice President Mike Pence narrows the Republican majority and moves the Senate balance to 52-48.

Sen. Jim Inhofe (R-Okla.), chair of the Senate Armed Services Committee, told reporters Wednesday that he plans to move ahead with a crucial defense-spending bill without provisions that would eliminate tech industry protections, defying a veto threat from President Trump.

Why it matters: Inhofe's public rebuke signals that the Senate could have enough Republican backing to override a potential veto from Trump, who has demanded that the $740 billion National Defense Authorization Act repeal Section 230 of the Communications Decency Act.

Uber is in advanced talks to sell its Uber Elevate unit to Joby Aviation, Axios has learned from multiple sources. A deal could be announced later this month.

Between the lines: Uber Elevate was formed to develop a network of self-driving air taxis, but to date has been most notable for its annual conference devoted to the nascent industry.
