Silver vs Rasmussen, Ctd


Building off a poll analysis by Mark Blumental, James Joyner defends Rasmussen:

Rasmussen was among the most biased, along with Fox.  Both have reputations as Republican-leaning.   But surprise! the venerable Gallup poll was off even more. In the same direction ... [A]nother not mutually exclusive explanation exists.  It turns out that Rasmussen’s results, which are robocalled, don’t include cell phones.   Neither do the Fox numbers.  That alone could account for a 3-4 point Republican skew.
