I found the Cincinnati Presidential Election data (for 1992 and 1996) at the Hamilton County Board of Elections Website
http://www.hamilton-co.org/boe/archiveresults.asp. Take a look at this.
City of Cincinnati, presidential election results 1992:
Clinton/Gore:
74,579 votes, 52.38% (WINNER)
Bush/Quale: 49,528 votes,
34.78%Perot/Stockdale: 17,026 votes,
11.96%Other: 1,261 votes,
0.88%Total: 142,394 votes
City of Cincinnati, presidential election results 1996:
Clinton/Gore:
74,739 votes, 59.72% (WINNER)
Dole/Kemp: 42,977 votes,
34.34%Other: 7,442 votes,
5.94%Total: 125,158 votes
Pretty cool, huh? Despite the county being solidly Republican much of the time, the city still has strong showings for Democrats during the nineties. Not much different than the city-county trend in 2000 and 2004. If you look at the city vote totals you can see the population decline (which is also a a sign of the it's deteriorating industry). The decline in the working class (I'm guessing which is probably more white) shifted the city roughly 7% Democrat, which
trended 4% Democratic than the nation that year.
FYI: As of the 2000 census, the city is 53% white and 43% African American.
An interesting detail is that from 1992 to 1996 (if you look at the 1996 Ohio presidential election results), many of Cincinnati suburbs swung slightly to the GOP ticket which is probably because of these disgruntled (again, probably white) working class people who tried to find work in the other areas of the Cincinnati Metropolitan Area, this theory is supported by the population increases that took place in the burb's from '92-'96.
Thoughts and opinions are appreciated!
