Then again, compare D.C. (around 89% Kerry) with Chicago and San Fran.

Perhaps it is simple absolute vote margin by county. Reno (Washoe, with over 150,000 votes) appears invisible, and it was 51% Bush - 47% Kerry in that county (7000 vote margin). This supports the total vote margin hypothesis.

The exact same thing is true of Albuquerque (Bernalillo County) which was 51-47, less than 10,000 vote difference, out of ~250,000 voters.

I think we have figured it out.
