Former governor of Massachusetts (1991-1997) William Weld. As a Republican, he's been criticized by many of his fellow party members for his un-Republican-like stances. He's pro-gay, pro-choice on abortion, and he endorses condom distribution in public schools. He'll talk with Terry about breaking rank with other Republicans, especially in light of today's partisan politics. Weld is also the author of a novel, "Mackerel by Moonlight" (Simon & Schuster)
