WASHINGTON  The roiling debate over health care this summer has included a host of accusations from opponents of the plan that have been so specious that many in the mainstream news media have flatly labeled them false.

Far from embracing the attacks, many leading conservative health care policy experts said in recent interviews that the dynamic was precluding a more robust real-world debate while making it nearly impossible for them to inject their studied, free-market solutions into the discussions.

And they said the focus on what they consider misleading or secondary issues was getting in the way of real questions about the plan they believed worthy of consideration.

“There are serious questions that are associated with policy aspects of the health care reform bills that we’re seeing,” said Gail Wilensky, a veteran health care expert who oversaw the federal Medicare and Medicaid programs for the first President George Bush and advised Senator John McCain in his presidential campaign last year.
