TALK: Controversial House Speaker Nancy Pelosi returns to SF to talk about and sign copies of her latest book Know Your Power: A Message to America’s Daughters. We're pretty sure it's about make-up and diet tips, but you'll have hear her tonight to find out for sure. And with a Whole Food just across the street, it'll be a Democrat's idea of paradise. (Oh, and be on the lookout for a possible Sheehan appearance. Fingers crossed.)
