1. If you want to be fully prepared for the Supreme Court’s decision tomorrow, I’d go with Kaiser’s full, detailed briefing – both what could happen to health care, and what could happen to the Constitution more generally.

2. Should the individual mandate fall, activists in California have a response ready: a new statewide single-payer system. Sarah Kliff on why that might really happen.

3. And a key point from Jonathan Cohn: While it is important, whatever happens tomorrow the fight over health care will go on.

4. Public opinion and health care, from Dan Hopkins.

5. Should Justice Scalia be forced to choose between being a judge and acting like a Fox News analyst? E.J. Dionne argues that Scalia has already made that choice, and therefore should resign from the bench.

6. I don’t want to make too much of political scientist Drew Linzer’s new poll-grinder and election-predictor, but for whatever it’s worth, his model has Barack Obama as an overwhelming favorite. Best to take this one and other predictors together to see where they’re collectively heading.

7. A very good point from Nate Cohn: “There is a high evidentiary burden for demonstrating that any candidate holds a structural advantage in the Electoral College.”

8. Important: the latest in the Republican War on Voting, from Ari Berman.

9. He’d rather have the reputation for ducking issues than actually have to have positions on issues …but Mitt Romney is definitely picking up the reputation. Here’s Scot Lehigh, who remembers a different Romney from the gubernatorial campaign.

10. Same topic: John Dickerson details the lack of details, and adds a bit of historical context. He sums it up: “To know what he will do, we must elect him.”

11. Some Crossroads fact-checking by Andrew Sprung.

12. Andrew Rudalevige on the Circuit Court ruling supporting the EPA.

13. Ed Kilgore is certainly right about this: There’s no reason for anyone to care – at all – whether various politicians show up for their party’s national convention, because there’s really no good reason for them to be there.

14. Michael Cohen on Barack Obama, the military and Afghanistan.

15. And why the candidates’ wives have to go through a cookie-baking ritual, from Jonathan Chait. Hey, it could be worse: Congress has to say the Pledge of Allegiance every day because George H.W. Bush’s campaign tried to paint Michael Dukakis as insufficiently patriotic back in 1988. Well, maybe that’s not worse, but wouldn’t it be nice if the media could ignore at least some of the nonsense?
