Sure, there's any number of small biases. But does that add up to a liberal bias as a whole? On the NBC Nightly News Brian Williams does anti-abortion activism from the anchor desk. Frequently. Is he liberal biased? Does the press take conservative economic claims and analyze them, or repeat them as though fact? A lack of any bias would say "Gingrich claims his tax cuts would create jobs, even though the Bush and Reagan tax cuts never created any jobs in the past." A conservative bias would say "Gingrich claims his tax cuts would create jobs." A liberal bias would say "Gingrich claims his tax cuts would create jobs but in fact will only redistribute wealth and run up the deficits." Or something to that effect.
And therein is the point. There's very very little that the press reports that can be said to be demonstrating a liberal point of view, much less bias. It just isn't findable. The mainstream press is far more neutral in the favor conservative truthiness than it is just neutral.
