It was already going to be a delicate moment of political theater an unpopular president offering a candidate he didn't really like an endorsement the candidate didn't really want. But the situation was made all the more awkward when George W. Bush went to the North Portico steps of the White House in March to welcome new Republican presidential nominee John McCain and McCain wasn't there. "So, anyway," Bush said to waiting reporters. "As I was saying..." Still no McCain. The president smiled. And then he did a soft-shoe dance. "I'm just going to tap dance the day away," he said. Minutes later, McCain arrived with wife in tow, and the tap-dancing president endorsed the tardy candidate.
