There are moments when Scott Brown evokes a 12-year-old boy who woke up one day in a politician’s body—as if the Tom Hanks character in Big had asked that fortune-telling machine for a Senate seat. He certainly has the 12-year-old’s vernacular. Stumping for John McCain at a small Christian college in March, the junior senator from Massachusetts opined, “If you told me five months ago that I’d be standing here in front of you, I would say, ‘You’re full of it.”’ He also has the 12-year-old’s gee-whiz sensibility. After learning that he’d made Time magazine’s list of the world’s 100 most powerful people, Brown exclaimed to The Boston Globe, “I didn’t realize it was in the world. … Lady Gaga’s number four, so let’s be real.” As a senator, he seems most excited by activities that appeal to the prepubescent mind. “As soon as his hip gets better, we’re going to do some bike-riding,” he said in April when asked about his relationship with his new buddy, John Kerry.
