Can you imagine kerry, gore, hildebeast, bubba or any of the kennedys doing this? I can't.
Never happen. There would be Hell to pay for the poor guys who were so unfortunate to have been on the scene. The dum dims can't appreciate the people who protect them (since we're all one big happy family, I mean)...
I once saw a video of Clinton getting ruffled by an adoring mob. He was purple with rage--not cool at all.
They may not have done exactly as W did, but I imagine John Kennedy and Ronald Reagan both thought highly enough of their Secret Service detail to have done something.
They would send someone to do it for them, but you better believe they would bring in their SS if they thought their precious lives were threatened. After all according to them, the world needs them. President Bush doesn't worry about himself, but he was worried about the agent and probably Laura as well. He's a good man.
