Goldwater was painted as a dangerous figure by the Johnson campaign , which countered Goldwater 's slogan " In your heart , you know he 's right " with the lines " In your guts , you know he 's nuts , " and " In your heart , you know he might " ( that is , he might actually use nuclear weapons as opposed to using only deterrence ) . Johnson himself did not mention Goldwater in his own acceptance speech at the 1964 Democratic National Convention
