It's what they DO, not what they SAY. Good rant from Seeing the Forest about the Bush lies. Excerpt:
Under the Soviet system, people came to realize that they could not trust government sources of news. They learned to look for what was being done. Under Saddam Iraqis learned to trust what they saw instead of what they heard.

By now the pattern is clear. By now we should all be learning not to waste our time and energy refuting their arguments. That's just getting yourself bogged down in the fog and smoke. That's just looking "over there" when they point their finger and shout, "Look over there!" Their "facts" and arguments are just trees. See the forest. The forest is this: they lie. They just lie. They say whatever their polls and focus groups tell them to say. Learn to see only what they do.
