President Obama continues his skid in the Gallup daily tracking poll, sinking to a 41/52 approval-disapproval split, both new records. It is now not unrealistic that he could slide into the 30s before midterms, especially considering he is continuing to bleed moderates/independents at an alarming rate.
The Real Clear Politics opinion poll aggregate shows President Obama with an average 45.3/50.7 approval/disapproval split.
