“Every two years the caucus could have a secret ballot on whether a chairman should continue, yes or no,” said Sen. Tom Harkin (D-Iowa), the chairman of the Senate Agriculture Committee. “If the ‘no’s win, [the chairman’s] out. “I’ve heard it talked about before,” he added."
Apparently what's good for the goose is not necessarily good for the gander.
