"There are times when we’re were among family, we’re among Democrats where we want to talk about being Democrats," said Obama in Florida.

"But today I want to talk to you a little about being an American, I want to talk about those things that bring us together as opposed to the things that drive us apart."

He went on to say that he had just visited a high school with [former Florida Governor Jeb] Bush. The crowd booed and hissed. 

Booed and hissed? In Obama's face? Just as he's talking about the things that drive us together as opposed to the things that drive us apart?!

Did Obama's own supporters ever take his Tucson speech seriously? And yet his opponents were supposed to moderate their politics at his behest.
