I got to witness something really special. About a dozen tea party activists had staked out Franken's booth, and confronted him loudly when he arrived. But within minutes, he'd turned an unruly crowd into a productive conversation on health care. The discussion went from insurance reform, to the public option, to veterans benefits, to cap and trade. He made a few laugh and even told a touching story that moved a few to tears. A whole lot of common ground was found.
