I normally think of cable news shows like Hardball as just sound and fury, signifying nothing, but once in a while the contrarianism produces something more substantive than the usual shouting match. Last night Chris Matthews departed from the fawning chorus that's followed Mike Huckabee since Wednesday's debate, and actually challenged his pious politicking. The answers are of secondary importance. The real story is that Matthews actually asked tough questions about faith's role in the campaign.
