Spending entirely too much time on a listserve today arguing about things that probably don’t matter. I’ll see if I can refrain this afternoon.

Here are some wide-open public midday news/views treats:

* August 6 GOP debate on Fox News could draw largest cable audience ever. After all, everybody loves to watch clowns!

* WaPo’s Balz & Costa say the candidates all have to have two strategies for August 6: a debate strategy, and a Trump strategy.

* New study notes residential segregation as strong as ever, though obscured by minority-majority inner suburbs and gentrifying city neighborhoods.

* Interesting TNR profile on pre-World-War-II French leader Leon Blum, “the first politician to embrace his Jewishness.”

* At the Prospect, a great explainer on Medicaid. More about that later.

And in non-political news:

* Scary data about solar storms and their potential effect on this here planet.

As we break for lunch, here’s some more early Buddy Guy with “Hoochie Coochie Man” in 1970. Not sure where the venue is; maybe some of you know or can figure it out.
