I was watching the McLaughlin Group over the weekend and heard Eleanor Clift predict (the final act in every show is "predictions") that the US Olympic team would be booed at the Athens Games.
Maybe it's because I live in Europe, but I wouldn't have expected anything else. I'd be shocked if any US athlete gets warm applause, unless they happen to first bad-mouth their country in the local press. I fully expected serious booing from the Greeks during the playing of the Star Spangled Banner (which thanks to the drugs scandals will be heard a lot less on the track this year).
