The key, I think, was Michelle's reaction to the streaker...

If she had appeased the streaker, she would have gotten the Spanish judge's vote. Had she climbed into bed with the streaker, she would have secured France's. She might have formed an alliance with the streaker to ensure a "thumbs up" from Germany. And, if only she'd dive-bombed the streaker she'd have the Japanese judge and...alas...the World Championship!
