Forget his stirring speech on Tuesday night. One of the most talked-about moments marking Sen. Barack Obama’s finally clinching the Democratic nomination was his fist-bump on stage with wife Michelle Obama.

Asked about the knocking of knuckles, Barack Obama said that despite all the publicity and stress, he and Michelle “still do silly things.” Indeed!

A fist-bump alone won’t carry Barack and Michelle Obama to the White House, but it does show that the aspiring commander-in-chief is actually kind of cool.

That factor sure didn’t hurt Bill Clinton in 1992. Just saying.

On the flip side of the coolness scale, we have President George W. Bush, who recently went chest to chest with an Air Force Academy graduate.

Okay, we hate to say it, but that was, maybe, just a little bit cool as well. Political opinions aside, we have to credit G-Dubs on his form …

An Air Force grad gets an appropriate send-off from the President.
