Rocker David Cook won the American Idol competition last night against balladeer David Archuleta. Cook outvote Archuleta by 12 million votes, a landslide triumph on his part. Cook was absolutely shock when host Ryan Seacrest announced that he won, maybe because he expected to lose due to the judges comments on him on Tuesday night, the American Idol Finale night. Simon Cowell praised Archuleta and announced that he won by knock out on the finale night. However, America have spoken and voted David Cook to be their American Idol.
