In defense of hypothetical questions.Michael Kinsley has a good take on the refusal of politicians to answer hypothetical questions -- and why they should. One of the better quotes:
A refusal or inability to answer hypothetical questions is nothing to be proud of. In fact, it ought to be a disqualification for public office. Anyone who doesn't ponder hypothetical questions all the time is unfit for the task of governing. In fact, it's hard to see how any halfway intelligent person can manage to avoid taking up hypothetical questions a dozen times a day.
