http://news.bbc.co.uk/sport1/hi/other_sports/olympics_2012/4553116.stm The article makes a huge assumption, but the gist is this: During the third round of ballotting, with the participants being London, Paris and Madrid, a vote was erroneously cast for Paris. The intended recipent was Madrid. This would have caused a Paris-Madrid tie, and a vote-off to determine which city was eliminated. The thought is this: London votes would have gone to Madrid, believing them easier to beat than Paris, Paris is then eliminated, and THEIR votes would have gone to Madrid in the final ballot. The belief is that would have been enough to put Madrid over the top, instead of London. Like I said, it's a huge assumption, and it ignores that Barcelona had the games in 1992, but I wonder why the story even goes out if there isn't a little something there.
