Hawkish anti-communist Democrat from New England or the midwest generally liberal and pro-labor on domestic issues but hardline on foreign policy. Voted for Dewey in 44 because said voter felt they would do a better job of confronting the Soviet Union and handling the post-war world then FDR who they saw as inexperienced at that point. Voted Truman in 48 due to being impressed with his foreign policy and generally agreeing on domestic issues. In 1952 was undecided at first and liked both Stevenson and Eisenhower but ended up going with Stevenson because even though said voter was a supporter of McCarthyism didn't see Eisenhower as committed enough to outweigh all other domestic concerns. Continued voting Democrat until 64 when after the bay of pigs he was even more radicalized and voted for Goldwater who he saw as taking the hardest line against the Soviet Union. Voted Humphrey in 68 who said voter generally agreed with and didn't see enough difference between him and Nixon on Vietnam to really prefer either. Nixon in 72 for obvious reasons, Ford in 76 due to a personal dislike of Carter and southern Democrats, voted Republican at the presidential level in the 80s then switched back to Democrats in the postwar world, Bush in 04 and McCain in 08 due to being hawkish on the war on terror before dying in 2010.

Were there any Goldwater-Humphrey voters?

It looks like there were many in the deep south. 

-Goldwater-Wallace voters were not in any sense Goldwater-Humphrey voters.

The counties that shifted from Goldwater to Humphrey can probably be explained by an increase in the black vote from 1964 to 1968.
