In 1972, Democratic campaigners handed out buttons with the slogan:
"Remember Oct. 9"

Why?

The pins referred to a speech Nixon had made
four years earlier (on October 9, 1968). In
it, Nixon had said, "Those who have tried to
make peace for four years and failed should
make way for new leadership"

Good going, Dawg!

In fact, I have one of those pins!
