>As everyone knows, I was no Bush fan. However, after Obama won the election, he had enough class to keep his mouth shut and not criticize the president elect. Our current president does not appear to have as much class. I do not remember an outgoing president who ever had the hubris to speak out against his replacement (Of course, Obama was doing this before the election. He has just continued his bad behavior afterward). Maybe this has happened in the past but I just do not remember it. Perhaps someone can refresh my memory...

I haven't seen Obama speak out against Obama since after the election - or maybe I missed it? Do you have any examples? All I've seen or read has been the exact seen the opposite.
All outgoing presidents campaign for their party during the election cycle - so this is nothing new. I haven't really seen any former presidents speak out against a new one - including this one.
