MR. PRESIDENT, WE MUST NOT ALLOW A WINE CAVE GAP! Wine caves and ‘purity tests:’ Warren and Buttigieg clash over billionaire donors:

Warren, 70, had earlier attacked Buttigieg for holding fundraisers in “a wine cave full of crystals” and suggested he was trying to buy the election in “smoke-filled rooms.”

“The mayor just recently had a fundraiser that was held in a wine cave, full of crystals and served $900-a-bottle wine,” said Warren. “He had promised that every fundraiser he would do would be open-door, but this one was closed-door. We made the decision many years ago that rich people in smoke-filled rooms* would not pick the next president of the United States. Billionaires in wine caves should pick the next president of the United States.”

“I do not sell access to my time,” the Massachusetts senator responded.

* Politicians are still making “smoke-filled rooms” analogies in 2019? Though as Jonah Goldberg noted in November, “There’s no doubt mistakes were made by those party fat cats and fixers, but those smoke-filled rooms also gave us Lincoln, Coolidge, the Roosevelts, Eisenhower, Truman, Kennedy, et al. I don’t love all of those guys, but it’s not obvious to me primaries would have given us better. And you can hardly argue that they weren’t democratically elected. (We can talk about JFK’s election shenanigans another time.)”
