Watching the Saddleback Forum, Fox's Gretchen Carlson was struck by John McCain's uncommon vulnerability. "I thought for the first time John McCain was revealing a lot of his personal side," she said. "You know, he doesn't like to talk about when he was a POW." It's true, he really doesn't. I remember, for instance, the grueling months of investigative reporting Jonathan Chait had to undertake in order to learn that McCain had been in Vietnam, much less spent years in captivity. Months spent unearthing, and reading, books John McCain had written about himself, and 12,000 word articles he'd penned on his captivity for US News and World Report, and jokes he'd told about his time spent "tied up," and commercials he'd approved with photos of him from prison. Truly, Chait is the Woodward of our time.
