Roy Moore has a theory. He says the Washington Post, which has been investigating his foundation and his conduct with teenage girls, isn\u2019t interested in truth. The Post, he argues, is just trying to take down his campaign. This is the kind of thing politicians often say, figuring it\u2019s a matter of irrefutable opinion. They don\u2019t imagine that a charge of political motivation could be factually debunked. But it can. And that is what has happened to Moore\u2019s theory.
