I’m pretty sure somebody has already done this, but just in case. . .
I have slightly modified the notorious 1964 LBJ “Daisy” commercial into a Donald Trump version. It’s only modified at the end graphics and narration. Available for use without restriction on YouTube
Daisy Commercial Donald Trump Version
The reason for doing this is based on Mr. Trump’s recent fascination with US nuclear weapons. I actually think Goldwater probably wouldn’t have used them. Mr. Trump is a much bigger wildcard than Mr. Goldwater.
