As Kathleen Parker noted today, the release of this report comes at a really lousy time for supporters of Obamacare.

A government report urging people to limit the use of a costly screening procedure that’s long been touted as a lifesaver should make people nervous when that same government insists that it must take over the delivery of health care to save costs.

It’ll only fuel suspicions that a primary feature of Obamacare will be big-time rationing.
