The worst I've seen is that he has continued many of W's policies - yet the same people calling him a dictator have yet to own up to any of W's abuses.
Under W we had election fraud, repeals of civil liberties, government-sponsored terrorism, fraudulent wars, private companies obtaining official governmental powers (a hallmark of fascism, incidentally), intolerance for dissent, and a whole host of abuses. Not so nowadays - conservatives are free to libel and slander anyone not part of their jihad.
So conservatives - is there any evidence? or are you merely going the Goebbels route, hoping to repeat a lie so often that it is taken as truth?
