It’s been one year since professional liar David Barton claimed to have an earned PhD, then pulled down the video where he made that claim after it was pointed out that his degree is from a diploma mill that awards them to Christian right stars and requires no work at all. Since then, he just doesn’t talk about it and refuses to answer questions about it or admit he doesn’t. “America’s premiere historian” can’t even keep his own history straight. Because lying is what he does.
