Neither John McCain nor Marco Rubio, two of Washington's mouthiest senators, could resist slamming Barack Obama for shaking hands with Cuba's Raul Castro at last month's funeral for Nelson Mandela.
"Why should you shake hands with somebody who's keeping Americans in prison?" asked McCain. "I mean, what's the point?"
Rubio's knock: "If the president was going to shake his hand, he should have asked him about those basic freedoms Mandela was associated with that are denied in Cuba."
