Chart of the Day: Follow the Bouncing Ball

Last week’s generic congressional poll from Gallup got a lot of attention because it suggested Republicans were ahead by a landslide with only two months until election day. And this week? Suddenly the parties are tied again.

I don’t think there’s any real lesson here except that these numbers can be pretty volatile. Maybe last week was an outlier. Maybe this week is. Who knows? But it ain’t over til the fat lady sings.
