Also quite laughable of an ad, because not only is it trying to compare Trump to a hard rightwinger like Goldwater, it is implying that Hillary Clinton can be compared to LBJ, which is even more laughable.
Remember also that LBJ was a fairly racist man himself, not one you would wish to compare yourself to like this ad does.

Goldwater supported Gay Rights and was pro choice.
Trump? Hah. Trump's not a hardcore right winger, of course. He's what I call an "authoritarian conservative," which is its own kind of radical deviation from the country's previous leadership (on both sides of the aisle) and his own party.
