A few obvious ones, but I'll go with the Iran story. We don't have the outcome yet, but surely it matters either way.
"Doesn't matter" is too strong, but VA-AG is certainly a combination of elements that give something far more attention than it deserves. I think it was Dave Hopkins who made the more general point on Tuesday that we tend to pay disproportionate attention to these off-year elections, and he's of course exactly right. Add to that an exciting, close election, and there you go.
What do you have? What do you think mattered this week?
