LOS ANGELES (AP) ‘ For an ‘American Idol’ season so flat and lifeless, the end sure rocked: Ex-bartender David Cook virtually body-slammed teen prodigy David Archuleta in a surprising landslide Wednesday night, capping an energized finale filled with big stars and polished performances. All that, and the imperious Simon Cowell was reduced to apologizing to Cook for casting him as an also-ran to Archuleta the night before. Turns out Cowell’s critique of Tuesday’s performances had limited influence: Cook, 25, from Blue Springs, Mo., swamped Archuleta, 17, of Murray, Utah, by a margin of 12 million votes out of the record 97.5 million cast by viewers. Cook was overcome with emotion, bending toward the stage after his name was announced. When he stood up, his eyes were filled with tears, the second time in as many nights that the scruffy, grainy-voiced belter had broken down. ‘The ride here has been pretty nuts,’ Cook said to a roomful of reporters backstage. ‘You couldn’t write this ‘ or maybe you can.’ For the final performances Tuesday, Cook refused to bow to the conventional during his three-song set, with Collective Soul’s ‘The World I Know’ as his pick for a closing song. He also sang U2’s ‘I Still Haven’t Found What I’m Looking For’ and the power ballad ‘Dream Big,’ his choice from the songwriting competition’s non-winning finalists. Judge Simon Cowell declared that those choices had sunk him, and told Archuleta that he’d scored a ‘knockout’ in the boxing-themed performance finale. But just before the winner was announced, Cowell uncharacteristically backtracked. He offered Cook an apology and said that the competition ‘wasn’t quite so clear cut as we called it’ ‘ even letting on that, for the first time, he felt either finalist would have been a worthy winner. Watchers had complained all season that, while the talent was solid this year, the entertainment quotient dropped ‘ and ratings had too, for a season average of about 8 percent. But the final contest turned that tide, with viewership for Tuesday’s show up 3 percent over last year, the network said Wednesday. That provoked a frenzy with a record 97.5 million audience votes cast by phone and text. Last year’s total vote count was 74 million. While Archuleta was showered with praise by the judges all season, online bookies and observers kept the faith with Cook. One Web site, which tracks busy signals on the separate phone lines dedicated to each contestant, projected him the winner correctly Wednesday morning. By strict ‘Idol’ standards, being rebellious turned out to be worth the gamble for Cook, whose hip and scruffy style and ability to work the camera with a soulful gaze also proved to have overwhelming appeal.
