Barry Goldwater was very pro-science. I feel confidant were he alive today, he would have fallen squarely into the "science in science class, creation in Sunday school" camp.
He married a liberal woman in his old age. In his sad latter years, Goldwater endorsed Roe vs. Wade, the gay agenda, and helped defeat a conservative congressional candidate in Arizona by endorsing his left-wing Democrat opponent. So no doubt that Barry Goldwater would have supported federal courts dictating policy to local school officials. But the 1964 Goldwater might not have, no matter what his personal beliefs might have been regarding matters that might come before them.
