Didn't the Democreeps do another ad like that not too long ago?
Indeed they did.
During the '64 election LBJ v. Goldwater, the dems portrayed AuH2O as a loose cannon.
They ran an ad with a little girl picking flowers in a field with mushroom clouds in the background.
I don't know if it won it for LBJ, probably not as LBJ was way ahead, but it swayed me.
They didn't fool me a second time.
