Those are Hustinis of America

I really hope we had somebody here who could interpret the polls. This is his approval according to polls
Poll Date sample approve disapprove spread
RCP Average 1/27 - 2/5 -- 45.1 48.6 -3.5
IBD/TIPP 1/27 - 2/2 885 A 42 48 -6
Gallup 2/3 - 2/5 1500 A 42 52 -10
Rasmussen Reports 2/1 - 2/5 1500 LV 53 47 +6
CBS News 2/1 - 2/2 1019 A 40 48 -8
Rasmussen reports poll clearly stands out. I checked their methodology, and looks like they conduct the poll via calling landlines, but they say they adjust for it somehow.
