I once read someone’s remark “They told me in 1964 that if I voted for Goldwater we’d end up in a land war in Asia. I voted for Goldwater, and, sure enough, we ended up in a land war in Asia”.
The mother who lived two doors up the street from us voted for LBJ in 1964. She voted for LBJ because he was the peace candidate and Goldwater was the war candidate. In 1968 her son was KIA in Vietnam.
