Well, there was that thing with ACA and the Supremes.
Syria again, and I guess the Iran sanctions.
For the new regulations on coal, see here. Not sure whether that means it matters or not.
The House budget vote was this week...certainly doesn't have any substantive importance (although I guess it does tell us what Appropriations will be doing on the House side), but it's another vote that people are going to be attacking this fall.
What else? What do you think mattered this week?
