Describe a Carter 1976/Dole 1996 voter

[Blow by blow, the passion dies]

Maybe a legacy segregationist who thought Bill Clinton was too liberal (by US definition)?

[TDAS04]

A conservative Southerner who voted for Carter for being a Southerner, but by the time Clinton came, it didn't matter anymore, they had become a loyal Republican.

[TransfemmeGoreVidal]

Southerners, also a lot of rural northerners who otherwise probably voted straight R

[Republican Party Stalwart]

Probably a white Protestant, most likely an Evangelical with a WASP ethnic background or a German Lutheran from someplace like the Dakotas. Voted Carter in 1976 for his unique standing as the "moral" or "anti-corruption" candidate (and/or for reasons in some way related to some combination of the various peculiarities and particularities of the circumstances of the 1976 election and whatever state their personal life was in at that time).

Also, an innumerable amount of things about a single person and their life can change a great deal in twenty years.
