One more time: Egypt, Syria. A bad week for coalition casualties in Afghanistan.
Let's see...a quiet week in the economy; don't know if that's a "dogs not barking" kind of what mattered, but perhaps.
We're waiting on more polling soon, but I'll repeat that I do think Rick Santorum is more trouble for Mitt Romney than Newt Gingrich (or Michele Bachmann) would have been...but less trouble than Rick Perry would be, if he managed to revive. I'm not sure whether that's really something that "matters" or not, but there definitely was movement in the GOP race this week.
No recess appointments, but Barack Obama will still have a couple of weeks after the holidays to do it. Or not. We did get new Fed nominees.
What else? What do you think mattered this week?
