Excluding the Rasmussen and Gallup overnight tracking polls, there have been seven major national surveys released this week. President Obama has recorded an all-time low job approval rating in six of the seven:

Quinnipiac 46%
Marist 46%
CNN/Opinion Research 48%
Ipsos/McClatchy 49%
CBS News/NY Times 50%
Bloomberg* 54%

Only one poll - FOX News/Opinion Dynamics - showed in increase in President Obama's job approval rating over the last month. In the current survey, FOX has Obama at 50% approval, up from his all-time low of 46% recorded in last month's poll.

The net result, of course, is that Obama has also reached an all-time low approval rating in the RCP National Average at 48.9%. Obama initially dropped under the 50% for the first time over Thanksgiving - he spent three days at 49.9% between November 25 and November 28.  After ticking up back over 50% right after the holiday break, Obama went under 50% again on December 4th and has remained there for seven straight days:

*Bloomberg has only measured President Obama's job approval in national surveys twice this year. President Obama's job approval was 56% in Bloomberg's other poll in September.
