Sometimes, the obvious things are correct. I'm confident that Barack Obama's decision on Afghanistan mattered; I'm confident that the New York Senate's decision on same-sex marriage mattered (for more, see Andrew Sullivan, natch).
As I said over at Greg's place, I don't really think that Eric Cantor's walk-out mattered much. I'm not sure I wrote that as carefully as I should have, though, so I'll clarify here: I'm not predicting that an agreement will be reached before default, or some (more likely) some other serious consequences for missing deadlines. All I'm saying is that eventually, they're going to raise the debt ceiling, and that in my view Cantor will have to support it. I should say, however, that while I'm figuring that at least a slim majority of House Republicans will eventually have to bite the bullet and vote for a higher debt limit, Stan Collender sees only about 100 of them doing so, and he might well be right.
The other one that I'll say didn't matter much were the Congressional actions and rhetoric on Libya.
I'm not sure about whether what David Petraeus said about torture this week mattered or not, but I'll steer you over to Adam Serwer and Conor Friedersdorf for more.
So, what do you think mattered this week?
