This morning Robert J. Samuelson cops to a bit of Obama buyer’s remorse in the WaPo–(“By Obama’s own moral standards, Obama fails”)–but those words are chocolates and flowers compared to Machinists Union President Tom Buffenbarger’s introduction of Hillary yesterday:

“He’s not just a trained thespian, he’s a terrific shadow boxer. You know the type. Outside the ring, he pretends he can float like a butterfly and sting like a bee. But Barack Obama is no Muhammad Ali. He took a walk every time there was a tough vote in the Illinois state Senate. He took a walk more than 130 times. That’s what a shadow boxer does. All the right moves, all the right combinations, all the right footwork, but he never steps into the ring. He walks away from the fight.”

For the record, I’d just like to point out this razor fight is between elements of the Democratic Party, the same party that sends emissaries onto cable news programs almost hourly to decry the cruel “Republican noise machine,” always on the attack because it is devoid of ideas. Is this what enrolling in the David Brock School of Etiquette gets you?
