Humphrey '68 - Bush '92 - Gore '00 counties

[SingingAnalyst]

Macomb, MI was a large one. Any other decent-size (or any size) counties in this category?

Montgomery, OH is probably one the bigger ones.

I suspect there are not many such counties, as there are few Bush '92 - Gore '00 counties except maybe in FL, and few Humphrey-Bush counties except in TX.

I can not give a 100% guarantee, but I'm fairly certain that Macomb was the only one such county.

Interesting. I'm not too surprised, but also might have expected a few small counties to slip in.

Macomb is conservative and pro-incumbent, and has remained so even with an increasing influx of ethnic minorities. The drop in crime between 1992 and 1996, as well as the changing of the guard in Detroit (from Coleman A. Young to Dennis Archer as Mayor) may have contributed to Macomb's 1992-1996 Dem swing. Macomb followed the national average almost exactly in each of the 5 elections from 1996 to 2012, breaking hard for Trump in 2016.

Oakland, MI would also have been such a county had about 1,000 Nixon '68 voters voted Humphrey instead.
