From around the web:
Dan Larison wonders why the conservative media is unwilling to call out lies by the McCain Campaign - Tell the truth? "Why do that when lying works so well for them"
James Fallows asks whether the media will treat obviously false claims by Palin in the same manner as they treated obviously false claims by Hillary Clinton.
Michael Kinsley asks, Why do Lies Prevail - the primary "reason is that no one - not the media, not the campaign professionals, not the voters - cares enough about lying."
