Describe a Dewey 1948-Stevenson 1952 voter

[TheElectoralBoobyPrize]

As someone else alluded, voters who prefer the more intellectual candidate. Or maybe voters who like governors/Washington outsiders.

Southern places would be places to look for R 64, D 68 voters.

Any swings towards Humphrey in the South were likely due to the VRA passing. It'd be hard to find Goldwater '64/Humphrey '68 voters other than people who just changed their politics.
