During the Democratic primary debate on Thursday, 2020 candidates were wielding the phrase “wine cave” like a sword to attack Mayor Pete Buttigieg for his high-dollar fundraiser with $900-bottle wine.

But while Buttigieg and Elizabeth Warren exchanged jabs over who had fewer ties to billionaires, many Americans were probably relating to Amy Klobuchar, who broke up their spat by interjecting: “I have never even been to a wine cave. I have been to the wind cave in South Dakota, which I suggest you go to.”
