Carter should of been the archtype democrat who could bring back the southern and/or conservative democrats back to the party. White evangelical southerner who grew up humble and had a folksy peanut farmer image. What explains why there were double of cross-party votes in favor of ford than the reverse?
Bigotry against Carter's religion.
Northern Democrats and SJW liberal hacks that decided to stick with the moderate they knew than some upstart Southerner with a hick sister and beer brewing redneck brother with these conceding conservative values. (And yet they allowed Clinton and Obama both of who are rightwards to this "conservative")
These people probably voted for Kennedy in the primaries next round, the switched to Anderson or...even Reagan.
