From the media matters website, in the past week I don't see anything he lied about. I see some distasteful comments -
"In my opinion, CNN and especially MSNBC delight in showing Iraqi violence because they want Americans to think badly of President Bush." Obviously he is assigning motives here where there may be none. And the use of the word "delight" is a little morbid, and I would say insulting to CNN and MSNBC.
"Secular progressives are going to basically tell children to use drugs, to have indiscriminate sex, do what you want when you're 14 years old, never mind what your parents think." That's some hyperbole there, and again, he's putting words in the mouth of people.
Going back a little further there is some "misinformation", as this website calls it.
From 10/11/06,
"South Dakota, as you know, has voted to outlaw abortions unless the mother's life is in danger, which is never the case, because you can always have a C-section and do those kinds of things." And later "Forty-five percent of Americans, according to a new CNN poll -- 45 percent say all abortions should be outlawed unless the mother's going to die -- or catastrophic health consequences, which again, is never the case -- never."
Obviously this is wrong. There are legitimate times when a mother's life may be in danger. Many people know this. But is he lying to try to sway that person who doesn't know or is he simply mistaken?
Beyond that, some of the misinformation quotes get older, which you specifically did not want. There seem to be a lot from 2004. My conclusion from this little bit of research (I don't have all day to sit here) is that he seems to create a lot of strawmen. He says things that are extreme and maybe unfounded, then assigns to them to whoever he disagrees with. He thereby comes out the victor.
Are these mistakes or dishonesty? Decide for yourself. He seems to be pretty intelligent to me, so I'm leaning toward dishonesty.
