The Associated Press "fact check" of Sarah Palin's new book wasn't enough. Now the left is just coming out and claiming Palin is a flat out liar. That was the argument made by Bella DePaulo in a Psychology Today blog entitled "Sarah Palin's Lies."

DePaulo, who has a Harvard Ph.D. in psychology and experience in analyzing lying, claims Palin excels at it. "From my post as an outside observer, it seems to me that Sarah Palin doesn't care much about the truth. In that way, she is a very special liar," she wrote in the Nov. 19 "Living Single" blog.

The article went on to say how "Palin seems to love the effect her disingenuous pronouncements have on her audience" and discounted Palin's comments about Obama "palling around with terrorists." (Apparently Psychology Today never heard about Obama's ties to William Ayers who "helped found the radical Weathermen, launching a campaign of bombings that would target the Pentagon and United States Capitol," according to The New York Times.)
