There is an old documentary of political ads titled "And If I'm Elected" (compiled for HBO in the 1980s, released on video) that was hosted by the Smothers Brothers.
It showed ads for all political perspectives and from a number of campaigns. The left ran some other scare ads against Goldwater as well (things with the KKK).
The Clintons just picked up the ball for LBJ.
It was in commercials co-created by our old fiends at moveon.org, the online petition site that said it was just about making sure Clinton wasn't impeached, but then became a springboard for Democratic campaigns against GOP figures in the impeachment process (primarily the House Managers).
The "Daisy" ad was created to imply Goldwater was going to push the red button despite the fact that the only President that has ever authorized the use of a nuclear weapon in combat was a Democrat (Truman).
