Should Opponents Of The Public Option Give Up Their Medicare?

Congressman Anthony Weiner (D-NY) posed an interesting challenge to Sen. Kit Bond and 54 GOP opponents of a public health insurance option yesterday: give up their Medicare, or give up their opposition to a public option.

I suppose it's possible that their opposition to a public option comes from first-hand experience with the horrors of "government-funded; government-administered single-payer health care - Medicare"... but I doubt it.
