A few phrases, like "that one" and "lipstick on a pig," achieved instant notoriety in the current election season after one of the candidates said them once and everybody pounced. But others seem to come up again and again just because somebody can't stop himself or herself or themselves.

a heartbeat away
Wall Street vs. Main Street
what he doesn't understand
the most important election in history
