Who Does Bloomberg Hurt?

No answers of course, just more fuel for the fire: a poll has Hillary winning Ohio with a 40% plurality if it's her, Giuliani, and Bloomberg. What's significant is that it's Ohio, one of those infamous "swing states." But I still have a feeling that should Giuliani win, he puts some traditionally blue states (Illinois, California, New York) in play, making Ohio more or less irrelevant.

Also: can anyone think of a state other than Virginia that has been so much a center of national politics? And that was in the late 18th/early 19th centuries.
