The most impressive aspect of Joe Biden's performance on Super Tuesday was its breadth, according to Dave Wasserman, House editor of the nonpartisan Cook Political Report, and NBC News contributor.

Why it matters: Biden won "urban voters, upscale & middle-class suburban voters AND rural/Appalachian voters. Just about the only places he didn't win were heavily Latino or progressive activist hotbeds like college towns."

The big picture: Wasserman reminds us that "a ton of the votes/delegates Sanders won ... are attributable to votes cast *before* SC and before Buttigieg/Klobuchar dropped out."

  • "And he still fell well short of Biden. That’s why this race could functionally be over soon."

More Smart Brevity from Wasserman's tweets, illuminating the power of momentum:

  • "The list of states where Biden would be poised to replicate tonight's success is pretty long: FL, GA, MD, MS, MO, LA, NJ, CT. In short, he's currently on track for the nomination."
  • "What the narrative that Joe Biden 'couldn't scale up in time for Super Tuesday' missed: no one can truly scale up for this bonanza & most primary voters aren't persuaded by paid media/field."

The bottom line: "There is a real chance, as in 2004, that Democratic primary voters won’t want to prolong these primaries and will rally around their presumptive nominee."

  • "The trajectory of the Democratic primaries is clear: it would take a miracle for Sanders to prevent Biden from becoming the nominee."

In her first sit-down interview since being named Joe Biden's running mate, Sen. Kamala Harris talked about what she'll do to fight for women if elected VP, and how the Democrats are thinking about voter turnout strategies ahead of November.

What they're saying: "In a Biden-Harris administration women are going to be a priority, understanding that women have many priorities and all of them must be acknowledged," Harris told The 19th*'s Errin Haines-Whack.

Facebook goes after Apple

Facebook is seeking to force a face-off with Apple over its 30% in-app purchase commission fee, which Facebook suggests hurts small businesses struggling to get by during the pandemic.

The big picture: Facebook has never publicly gone after Apple, a key strategic partner, this aggressively. Both companies face antitrust scrutiny, which in Apple's case has centered on the very fee structure Facebook is now attacking.
