What would you ask Mayor (of NYC) Bloomberg? 
lionhearted: I'd be curious how he balances his wealth and investments with being publicly elected - I know the U.S. President has to put most of his investments into a blind trust or some such once elected, what's it like for the mayor of NYC? Lots of old associates must want his council, lots of people must want him to invest, and so on. It must be a challenge to manage that and his post.If I asked along these lines, I'd take a long, long time to make sure it was phrased in a very friendly way - if it comes across minorly accusing, even at all, you'll probably get a politician non-answer. Heck, you might anyways. But I'd be fascinated to learn how someone balances being a billionaire and running one of the busiest cities in the world.
