Elizabeth Warren  is running for office in the most high-profile race in the country not involving Barack Obama. It's a position that calls for some tact. So what does she think about the Occupy Wall Street protests that are roiling the country?

"I created much of the intellectual foundation for what they do," she says. "I support what they do."

Warren's boast isn't bluster: As a professor of commercial law at Harvard and the force behind Obama's consumer-protection bureau, Warren has been one of the most articulate voices challenging the excesses of Wall Street. Still, she enjoys an outsize celebrity for an academic and bureaucrat: a favorite guest of Jon Stewart, Warren, 62, has become a hero to the left, a villain to the right, and a fascination for everyone in between. Now that she is challenging Massachusetts Republican Sen. Scott Brown, she has emerged this year as a poster child for what some of America loves, and an increasing swath of America hates, about the president.

No one else has Warren's gift to send the right into a sputtering frenzy.
