Rasmussen has long been an outlier in the Presidential approval polls, and I have been skeptical of them since last year. Still, it's believable that things are heading down for Obama and the Dems. Anyone know what their 'likely voter' model does, and if they still do landline robocalls-only? Both of these could affect their results.
Update. Here is an illustration of why I am skeptical of Rasmussen:
A new Rasmussen Reports national telephone survey finds that 37% of voters now favor her confirmation while 43% are opposed. (7/15) For the past 2 weeks, they have found more opposed than support.
