Barack Obama has seemed, at times, too unwilling to throw a punch. Maybe that is changing. In the same Orlando, Fla., speech to the annual conference of the Veterans of Foreign Wars in which he tantalizingly dropped Joe Biden's name, Obama opened fire:

"For all of his talk about following Osama bin Laden to the Gates of Hell, Senator McCain refused to join my call to take out bin Laden across the Afghan border. Instead, he spent years backing a dictator in Pakistan who failed to serve the interests of his own people," he said.

And later:

"Let me be clear: I will let no one question my love of this country. I love America, so do you, and so does John McCain."

That's the stuff. More, please.
