Howard Kurtz: Are the media biased against Howard Dean? Those who think so are getting some new ammunition today. The New Hampshire exit poll that the major networks are using today asks mostly straightforward questions: Are you male or female; white, black or Hispanic; liberal, moderate or conservative? Who did you vote for? When did you decide? Did you pick your candidate because you think he can defeat George Bush or because he agrees with you on the major issues? But on one of the two questionnaires being used, there's this zinger: "Regardless of how you voted today, do you think Howard Dean has the temperament to serve effectively as president?" That, of course, raises the possibility that he might not, and the results could be cited endlessly in the primary coverage.
