Earlier this year, Fox News switched its polling firm from Opinion Dynamics to Anderson Robbins Research (D)/Shaw and Company Research (R), a joint bipartisan collaboration.

This change has produced a shift in the Fox News poll. Previously, it was usually on the right hand side of the RealClearPolitics’ average of Obama’s job approval, along with Gallup, Quinnipiac, and Rasmussen. Lately, however, it has fallen on the left, mixed in with polls from major media outlets.
