Mitt and Ann Romney were sitting up front at the big bout between Manny Pacquiao and Juan Manuel Marquez.
As guests of the Nevada Athletic Commission, Mitt visited Pacquiao before the fight in the dressing room to wish the boxer luck.
"Hello Manny. I ran for president. I lost," he told Pacquiao.
Pacquiao went down when a thundering right hand from Marquez knocked him out cold. It was a dramatic, shocking moment, and the crowd went nuts.
