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.

Give me a racist that is willing to fight his own wing of his own party, tooth and nail, to bring civil rights and voting rights to people who have been disenfranchised for centuries. Actions speak louder that words. Lincoln himself had some unsavory viewpoints on race, but his actions are much more important.
