Sudden jump for O-bummer in Rasmussen daily poll -- ?Que?

[Ithaca-37]

Naturally, it means nothing is not sustained, but I wonder how The One jumped from negatives solidly in the teens to suddenly into mid-single digits.  I've heard nothing to explain that jump.  Maybe it's all smoke, because if it was a genuine trend, then it would be trumpeted all over the traditional news media.

Am I missing something?
