Why I Like a Liberal Media

As I've said before on this site, the liberal media does Democrats more harm than good. James Taranto makes a similar point today on OpinionJournal. Referring to an obviously bias headline from CBS, Taranto says:

Of course, this doesn't really serve the interests of liberals, since it reinforces their prejudices by misleading them into thinking most Americans share them. If most Americans think Iraq will succeed, is that going to lead them to vote for a party that is rallying around a defeatist like John Murtha?
