"Marianne Williamson" is an American politician, author and activist. Because "Marianne Williamson" is someone who cares about living a healthy lifestyle, and "polenta" is a healthy food, the speaker is making a joke that she talked about "polenta elbow" during her political campaign. "Marianne Williamson" did not actually talk about "polenta elbow" during her campaign.
