no where does that say they admit their method is faulty

OK, let's see if I can explain this...
Approval Ratings are based on the general population, unlike polls used to predict election results.
Pretty much the only reason approval rating polls exist, besides just getting a general feel for things, is so that they can be compared against
other president's approval ratings from the same period.
Which is exactly what the right is currently doing with these approval ratings.
Since Rasmussen didn't use the "Likely Voter" methodology in any approval rating polls prior to Mr Obama, and since they are claiming that the current approval ratings they list show a dramatic downturn in Mr Obama's general approval ratings, they are using false figures to represent their claims.
Get it?
