Some liberals I know of revere Bill Maher. They consider his movie “Religiolous” (sp?), which denigrates religion, to be a very thoughtful incisive movie.
Trying to say, he may be an inane comedic personality, but some people take him seriously.
Most liberals get their news from Jon Stewart and their talking points from Bill Maher. To say that liberal comedians don’t have influence is ridiculous. Sure, they don’t have a fraction of the influence of Rush, but it’s not Rush’s fault that they are so incompetent.
