From Eric Dondero:

A slew of new poll numbers have come out for Obama in the last couple days; Rasmussen, Quinnipiac, CNN and CBS. All point downward. Of particular note, usually reliable Obama backers, CBS finds him at only 46% approval to 41% disapproval. Rasmuseen has him in negative territory at 46% approval to 53% disapproval.

It all adds up to a culmulative Real Clear Politcs average of 47.6% approvals. That's compared to 45.8% disapprovals.

That is the lowest level of support recorded for Obama in the running RCP averages ever.
