Goldwater, once the arch-conservative, preferred Gore in the 2000 election. Goldwater didn't change his views, the Republican Party did.Actually, Goldwater remained neutral in the 2000 election, and was not heard to express a preference for either major party candidate for the excellent reason that even before the summer's nominating conventions he'd been dead for over two years.
I do believe, though, that he would have detested Bush's grotesque cabal, and wouldn't have been shy about saying so.
