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.
