* The Post editorial board makes a strong case for the constitutionality of the mandate, one rooted in the size and urgency of the problem it would solve, and in Congress’s power to regulate harmful inactivity.

* The Atlantic has an extensive and useful primer on how the Supreme Court has ruled on the Commerce Clause , and on the central question of how its power has been interpreted.

* Did Chief Justice John Roberts tip his hand in favor of Obaamcare by dismissing the idea that there’s a distinction between the mandate and the fine that would enforce it?

* Orin Kerr has more on the meaning of that moment:

The challenge to the minimum coverage provision is premised on the idea that the mandate is really a genuine mandate, not just some sort of generalized incentive, and that argument rests in significant part on seeing the mandate as separate from the penalty. We’ll have to wait and see tomorrow how many Justices accept that framing of the statute.

* The case that Obamacare is unconstitutional sounds increasingly like an argument designed to justify the predetermined position that Obamacare just has to be unconstitutional.

* Pew finds that slightly more approve of Obamacare than disapprove of it, 47-45, though that’s within the margin of error. But 56 percent disapprove of the mandate.

* Amy Walter argues persuasively that no matter how SCOTUS rules, health care won’t be a key driving issue this fall.

* Steve Benen details the multiple reasons why the attacks on Obama’s “hot mic” moment are more heat than light.

* Michael O’Brien warns Republicans: Live by the price of gas, die by the price of gas.

* A Suffolk University poll finds Obama leading Romney nationally by 47-37, though horse race numbers mean little at this stage. Perhaps the key finding is that Romney’s favorables are upside down at 38-44.

* The real impact of Romney’s ongoing problem with evangelicals is that it will force him to keep embracing positions designed to connect with them that could repel swing voters this fall.

* And some on the right hated it, but Trayvon Martin’s father tells Time he appreciates Obama’s brief statement about his slain son:

“It felt really warm to know our son’s name had been mentioned by the President of the United States...His name is ringing all over the country, all over the nation, all over the world.”

Much more from Trayvon’s parents in the rest of the interview.
