Is the U in USA a reality?

An American friend I was talking with yesterday suggested, only half-jokingly, that those states which support the war and return Bush electors should be split off from the rational "sensible" states that can see past the war rhetoric, and left, as a separate country, to the tender mercies of the GOP's economic policies.

He pointed out that those states which vote for Bush typically produce the lowest Federal tax revenues and receive the largest Federal subsidies. All the time whining about the evils of "big government" and "socialism". The only problem I see with that problem is that the Democrats in those states would suffer (as well as innocent children). It may be, though, that the "United" part of the USA is actually a fiction - it seems to me that much of New England has more in common culturally with Toronto than it does with Tampa (to take two T-cities at random). In fact, should the USA try to preserve a unity which seems to be rapidly disintegrating, and where the U is as illusory as the U of the USSR? I'd be interested to see what anyone thinks about of the future unity of the USA.
