Consistent 20% trends election-over-election at the county level?

[phk]

Inspired by this thread. https://uselectionatlas.org/FORUM/index.php?topic=105389.0


Have there been any counties that have trended 20%+ D or R in an election recently and done the same the next election?

It hasn't, but Clayton County Georgia has seen drastic shifts

1984 Reagan 72.84-27.16
1988 Bush   65.43-34.05
1992 Clinton  44.65-41.33
1996 Clinton 55.55-37.34
2000 Gore 65.21-32.52
2004 Kerry 70.49-29.03
2008 Obama 82.93-16.59

There must have been a major change (although probably not as much as the change in result) in the demographics of that county during that period.

Well, yes:

http://en.wikipedia.org/wiki/Clayton_County,_Georgia

1980 Census population 150,357, 91% white, 9% everyone else
2006 Estimate population 271,240,  62.1% black, 20.4% white non-hispanic, 11.3% Hispanic, 5% Asian

The number of votes cast has gone from 43 thousand in 1980 to 99 thousand in 2008

It's major change
