Politicians Break Promises, Even Their Wives

From Obamafoodorama:

In an interview with the New York Times given the day before the groundbreaking [of the White House garden], Mrs. Obama announced that the entire First Family, including President Obama, would be pulling weeds in the Kitchen Garden, “whether they like it or not." With one exception.

“Now Grandma, my mom, I don’t know,” Mrs. Obama said of her mother, Marian Robinson, working in the Kitchen Garden.
Mrs. Robinson "would probably sit back and say: “Isn’t that lovely. You missed a spot,”" Mrs. Obama said.

 But when an aide was asked about follow-through:

The aide said she wasn't aware of any Presidential or First Daughter weeding or harvesting action, but added that it might be going on "during private family time."

"You never know," the aide said. She added that Mrs. Obama, in her interview, "may have been joking" about the First Family weeding the Kitchen Garden.

  If I remember correctly, I was always dubious about the premise.  Given the schedule I presume Mrs. Obama maintains, it would be very hard for her to herd her family to the garden on a regular basis.
