I'll take an easy and obvious one: the GOP retreat on the debt limit. If you thought that was a sure thing all the time, then you may not think it mattered; I thought it was at least a solid possibility they would run right up to it, and do at least a bit of harm to the economy.
Democrats admitting they'll vote for the president's nominee for Secretary of Defense? No great surprise there, to me. The real ballgame there has always been whether 60 votes would be required, and if so whether Hagel can get five Republicans. As far as I know from the coverage, we don't know that part of it yet.
So that's what I have. What did I miss? What do you think mattered this week?
