Obama Vs. Bush

Maybe my memory is just selective, but I don’t remember President Bush using the authority and constitutionally derived power of his office to attack CNN during his time in office. Oh, I’m sure he said a comment or two that could be considered that way, but never as an active and concentrated policy. For some reason having the President act this way comes off as rather tyranical- isn’t this the type of stuff they do in poor improvised brutal dictatorships?
