At the very least, there's actual evidence that he's a liar:
-------
In his November 10 interview with Sean Hannity, Moore said he remembered Gloria Deason and Debbie Gibson, who told The Washington Post he had dated them when they were teenagers and he was a local prosecutor in his 30s. Although he did not recall dating them, Moore said, "I'm not going to dispute anything." He described Deason, who said she dated him when she was 18, as "a good girl." He said he knew "her parents, her mother in particular." He denied her account that he gave her wine in restaurants before she turned 19, then the minimum drinking age in Alabama, claiming (falsely) that it was not possible because Etowah County was dry at the time. Regarding Gibson, who told the Post she dated Moore when she was 17, he said, "I know her, but don't remember going out on dates. I knew her as a friend. If we did go out on dates, then we did."
Last week, in two separate campaign appearances, Moore changed his story. "The allegations are completely false," he said on November 27 in Henagar. "They are malicious. Specifically, I do not know any of these women." He repeated that blanket denial on November 29 in Theodore: "I do not know any of these women, did not date any of these women, and have not engaged in any sexual misconduct with anyone."
