Just a quick thought to share. Many people have latched on to the “Cheney lied when he said that he had never met Edwards” bandwagon.
What is significant about that? Why is that important? There is no doubt that politicians meet hundreds if not thousands of people, so it wouldn’t be much of a surprise if they did not remember everyone they had met.
If you want to go after Cheney there are lots of ways that offer more substance. To me the aforementioned complaint is similar to saying that he is a bad guy because he likes corned beef with mayo. Certainly not something that I would eat or endorse eating, but not a meaningful way to judge the character of a person.
