Putting the question to libetarians

Do you believe in the secret ballot? If so, I think you're going against, and implicitly recognizing the self-defeating nature of, libertariansm. If not, please explain how your philosophy is not merely a stalking horse for plutocracy.

NOTE: enabling the voter to choose to verifiably reveal her/his vote counts as doing away with the secret ballot. Because it enable employers to require that their employees do so.
