It is a line I have used to open speeches on the lecture circuit for years and it never fails to get a laugh: “I’m happy to be here tonight from Washington, D.C., where the only politicians with convictions are in prison.”

That’s only partially true. Democrats have convictions. They know what to do with power when they get it and how to isolate, even punish, any member of their party who dares to take a different position on an issue. Republicans seem to constantly react to the policies of Democrats or slam each other instead of making a case for the superiority of their ideas. It doesn’t help Republicans that they lack the Democrats’ uniformity.
