Fox News calls out Romney's "studies", misses the point

In an interview with Romney surrogate Ed Gillespie, Chris Wallace of Fox News questions the reliability of the studies.  He says the studies should be doubted since some are op-eds and blog posts, and they are from right-leaning sources.  Analysis from potentially-biased sources should of course be taken with a grain of salt.  But these studies are not merely to be doubted because of their authors and their possible biases.  They are to be ignored because each is based on different assumptions than Romney's plan and/or they are just plain wrong.  Wallace deserves credit for casting a skeptical eye on the studies.  He errs, however, because he casts the issue as right/left, not right/wrong.
