It's more economy and budget stuff, right? Early in the week, the resolution of the latest showdown; at the end of the week, a not-terrible employment report and then the S&P downgrade. I suppose all of those qualify. I don't think that the stock market's volatility does, much. I wrote a quick item over at the Plum Line about that, but here I'll link to what Nate Silver said. The economy matters a lot to elections, but day-to-day stories about the economy fade really quickly. Of course, this item isn't just about what matters to elections, but either way I'm not going to argue for Thursday's adventures on Wall Street mattering.
What else? The terrible news from Afghanistan this morning, for one thing (it's important regardless of any longer-term effects, but it also pushes the Administration a bit in the direction of withdrawing, I'd say). If you want some good news, it's starting to look as if the recent spike in US deaths in Iraq may have been confined to one awful six week period, with 20 fatalities through July 17, but none in the almost three weeks since.
I'm behind in my newspaper reading, however, so I'm sure I'm missing things: What else? What do you think mattered this week?
