Europe, again, especially Italy and Greece.
Ah, we had an election, too! Or, more properly, lots of elections, many of which mattered a lot to the people whose lives will be directly affected by the results. I'd be very cautious, however, about extrapolating at all. It was a good day for the Democrats (although hardly a landslide; the Dems did well at a few high-profile elections and ballot questions, but there was a lot of status quo elsewhere). But it probably means just about zero for 2012.
And the continuing troubles in Syria and Yemen shouldn't be forgotten, either.
So, what do you think mattered this week?
