This is actually a topic about the Senate, rather than a particular issue. A few questions came to mind as I was procrastinating getting work done on some book chapters: (1) Have you ever changed your opinion on an issue based on discussion here? If so, what issue and why? (2) If you haven't changed your position on anything, why not? Is it an evidence question? A gut-instinct question? A religious/metaphysical question? I'm curious to know. (3) What would it take for you to change your opinion on an issue?
