...and they've only added 100 new responses to their rolling average.

That's a double-digit margin-of-error on the daily sample... so it's very likely that you'll see big swings even if the real race doesn't change at all.

My guess is that Sestak closed the race to about three points over a week ago and it hasn't changed much since then. Close enough for a big GOTV surge into election day... and/or a better-than-expected national environment.
