A primary is a completely different ball game than a general. He'd probably have to run as an independent though. Before you scoff at the idea, remember Ross Perot? He garnered quite an impressive amount of support for a psychotic rich guy out of nowhere.

In the end, Giuliani would win, but Lieberman I think would do well enough to chip away at the ridiculous two-party system.

But then, if we lived in a world where Lieberman and Giuiliani could both get nominations, I probably wouldn't be critical of the two-party system as it stands anyways.

Well, it is just my fantasy election, in any case. I do not understand politics well enough to comprehend why it is consistently the case that, out of all the potential people in the country, the parties cannot put forward half-decent candidates.
