A two-part Need to Know this week begins with the American Enterprise Institute’s James C. Capretta, who knows everything there is to know about Obamacare and related questions. Mona asks him about the Aetna decision to withdraw from exchanges and what the state of the law is generally. He’s not optimistic, but then, who is?

Jay then joins from Salzburg (within sight of Mozart’s home) to discuss Louisiana flooding, Bill Clinton, music, what we expect of politics, and many other subjects. The one topic not covered: Trump. Everyone needs a break from time to time.

The music, apropos of Salzburg, is Mozart’s Requiem.
