(forwarding for Barry Alpert)
Just encountered this germane formulation, but am skeptical whether it holds up to rigorous analysis. 
At a raucous rally in a high school gymnasium in Nashua, Clinton skewered Obama for several votes he has cast in the Senate, such as his vote in favor of the Patriot Act and for energy legislation she described as "Dick Cheney's energy bill." She never mentioned Obama's name but left no doubt about whom she was discussing.

"You campaign in poetry, you govern in prose," Clinton said.
