I'll guess in North and South Dakota the biggest Dem swing in ND was Steele and in SD was Ziebach.

in Minnesota I'll guess Beltrami was the biggest swing toward Kerry and Anoka the biggest swing toward Bush.

No more time now to complete this, but you're right about the Dakotas, wrong about MN. Far off, even.
Beltrami swung to Kerry by 7,5 - Mahnomen by 17.3
Anoka swung to Bush by 6.1 - Isanti by 8.6 (okay, that one's not that far off, but Anoka's not in the statewide top 5).

Too many counties swinging either way in MN and IA. Not really that many counties swinging Rep in the Dakotas - I could have drawn up a list but couldn't be bothered (all the major population centers would have been on it, btw).
Counties swinging Dem in MO: Adair, Chariton, Mercer, Oregon, Perry, Putnam, Reynolds, Sainte Genevieve, Saint Louis county, Saint Louis city, Schuyler, Scotland, Sullivan

Maryland counties swinging Dem: Charles, Howard, Montgomery, Prince George's
West Virginia counties swinging Dem: Calhoun, Pendleton, Roane, Tyler, Wetzel; plus Mason which didn't swing at all
Georgia counties swinging Dem: Bibb, Chatham, Clarke, Clayton, DeKalb, Fulton, Henry, Richmond, Rockdale
Florida counties swinging Dem: Collier, Duval, Gadsden, Hamilton, Hendry, Jefferson, Leon
I didn't do NC and SC lists because there were too many either way. There were too many either way in Virginia as well, but I made a list anyways:
Virginia counties swinging Dem: Albemarle, Alleghany*, Brunswick, Chesterfield, Cumberland, Fairfax, Greensville, Henrico, Highland, Lancaster, Loudoun, Lunenburg, Mecklenburg, Nelson, Northampton, Northumberland, Patrick, Pittsylvania, Prince William, Rappahannock, Rockbridge, Sussex
Virginia cities swinging Dem: Alexandria, Arlington, Charlottesville, Danville, Emporia, Fairfax, Falls Church, Fredericksburg, Harrisonburg, Hopewell, Lexington, Manassas Park, Martinsville, Petersburg, Richmond, Williamsburg
*The city of Clifton Forge lost its independent status and became a part of Alleghany county between 2000 and 2004.
Comparing the Alleghany result 2004 with the Alleghany result 2000 renders a 1.0 Dem swing.
Comparing the Alleghany result 2004 with the combined Alleghany and Clifton Forge result 2000 (certainly the more sensible thing to do) renders a 5.5 Rep swing.

Went from 59-39 Gore to 59-39 Bush.

Went from 59-39 Gore to 59-39 Bush.

Weird. Any idea why?

No. But I must say I find the Kentucky goings-on much weirder, mostly because they affect a much larger area. Lake is at the far Northeastern end of Tennessee, with the next couple of TN counties voting Republican in 2000...guess it just became more like its neighbours...
Speaking of wierd: unless these are incomplete data, turnout fell by quite a bit in a fair number of West Texas counties.

[minionofmidas]

I think I'll wait with the Mountains until the Colo. results have been updated. They seem to include a number of counties with incomplete data. (I've done Montana, Idaho and Wyoming, actually.)

[minionofmidas]

Speaking of wierd: unless these are incomplete data, turnout fell by quite a bit in a fair number of West Texas counties.

Which area?  They had snow in the Panhandle on election day.

Loving (yeah, smallest county in the nation). Culberson. Brewster IIRC. One or two more that I forgot, presumably more where I just didn't notice. So, more like Big Bend country than Panhandle.

Re: Engineer. Yes, some of those Dem "swings" are pretty much statistical flukes. Happens in all the states. Happens for some Dem counties, too, I'd guess.

Mountain
Top 5 Dem swings
San Miguel CO 27.7
Boulder CO 26.3*
Archuleta CO 23.3
San Juan CO 21.6
Teton WY 21.3

The Boulder result is flawed on two counts. a) Broomfield County was created out of parts of three counties including Boulder, and voted well more Republican than Boulder. (It's missing on Dave's county map, btw.) Boulder result 2000 is including parts of Broomfield. b) The number of votes cast is well down, even when taking Broomfield into effect. Alcon found some newer Boulder data elsewhere (I haven't been able to find data at the Secretary of State's website myself) which would show the swing to be some ~6 points less.

Except for Kootenai, all the Northern and Empty Center counties swung Dem.)

I didn't do a Colorado list, but, very roughly, anywhere East of the Rockies swung Rep, anywhere in or West of the Rockies swung Dem.

Census estimates for Culberson County show a pretty sharp drop in population (10% since 2000) after holding fairly steady for 30 years.  This might be due to some oil and gas going out of production, or maybe a gypsum processing plant or similar.  The only other industry is services for Interstate I-10.  Van Horn is the largest town for about 100 miles either way.

Culberson was in the news over here for a population increase actually...some German artist colony. These guys bought up the ghost town site of Lobo, due south of Van Horn.
I don't think it had been a ghost town for long though. (Plus of course, Germans can't vote in America.)

Does anyone know the top Democratic swings in counties where Nader was irrelevant?

So basically you're looking for the strongest drop in the Rep vote?
