Edit: Keep finding bigger ones!
Coal County, Oklahoma, went from Bush +7 to McCain +48, a 41-point swing. Which is, coincidentally, insane.
Not for a county with all of 2200 voters.
We should have a category for counties with more than 25,000 votes.
Meanwhile, check out the college counties in Indiana:
Tippecanoe, IN (Purdue): Bush +19 to Obama + 11 (30 points)
Delaware, IN (Ball State): Bush +14 to Obama + 15 (29 points)
Monroe, IN (Indiana U.): Kerry +8 to Obama + 33 (25 points)
Vigo, IN (Indiana State): Bush +8 to Obama + 15 (23 points)
St. Joseph, IN (Notre Dame): Bush +2 to Obama + 17 (19 points)
That's a fantastic statistic.
It also portends ill for the GOP. The State colleges churn out teachers, which implies that schools will be inundated with Bush-bashers for decades among those born in the 1980s and 1990s. Schools are the incubators for political values. But even among non-teachers, that implies that even those young adults who go into private industry are less likely to put some right-wing bumper sticker on the bumper. That includes Purdue, which has a fine engineering school.
Anything on Steuben County, which has a small university (Tri-State, as it was then known)?
The GOP absolutely must redefine itself to have relevance beyond current times.
Contrary to the image that one gets of Notre Dame University as a university of cultural and intellectual importance (it is!) it is really a small school, and St. Joseph County is very much an industrial area.
