1 big thing: Beto busts through
In a crowded scramble, Beto O'Rourke broke through in a way most candidates could only dream of with his 2020 entry this morning.
The big picture ... For a candidate polling in the single digits, O'Rourke has a huge national profile, as shown by the instant response to this morning's announcement.
Drudge banner: "BETOMANIA"
Trump mocked his announcement video: "“He has a lot of hand movement -- I’ve never seen anything like it ... Is he crazy or is that just the way he acts?”
Pelosi: “Beto has brought a good deal of vitality to Congress ... when he came, he came as a real champion for the environment.”
Early House Democratic endorsements: Stephanie Murphy (D-FL), Kathleen Rice (D-NY), Veronica Escobar (D-TX) and Sean Patrick Maloney (D-NY).
Between the lines: "If there’s an elevator pitch for O’Rourke’s presidential candidacy, that’s more or less it: 'I came this close to turning Texas blue. Imagine what I could do nationally,'" FiveThirtyEight notes.
"O’Rourke won big in cities like Dallas, Houston, Austin and San Antonio. Not just that, but Texas saw an astounding 3.7 million more votes in 2018 than it did in the midterm elections four years earlier."
"O’Rourke outperformed Hillary Clinton by about 6 percentage points in the state."
What's next: Beto's formal campaign kicks off in El Paso on March 30.
In the meantime, pay attention to whether his campaign releases early fundraising or volunteer numbers. The current leader on those metrics is Bernie Sanders, who hauled in $5.9 million in his first 24 hours.

3. First look: New Apple ad uses humor to push privacy
Apple is pushing its privacy message with a humorous ad that will debut in prime time Thursday and runs through the three weeks of March Madness.
The tagline: "If privacy matters in your life ... It should matter to the phone your life is on."
The ad aims to use relatable moments from daily life to show how naturally inclined we are toward privacy:
In one scene, a guy chooses a urinal but then quickly slides down the row when he notices someone else nearby.
When a woman catches someone staring at her as she puts on makeup in traffic, she coolly rolls up the window.
In a diner, two customers stop talking when the server approaches.
Be smart: Apple sees privacy as a way to differentiate itself from other tech companies, since its business model depends on selling products rather than data.
Reality check from Axios' Ina Fried: Apple takes a number of steps to protect user privacy, for sure. But many of the most-criticized apps and services run on its devices.
