Jonathan Gruber, a health economist at MIT, has drawn considerable attention for his advocacy for President Obama’s coverage expansion efforts and, more recently, for his insistence that Gov. Romney’s state-level coverage expansion was essentially indistinguishable from PPACA. Described as a “former Romney advisor,” Gruber’s charges were very well-timed. Gruber has also served as an analyst for the Department of Health and Human Services during the Obama administration, as the progressive blogger Jerome Armstrong observed in January of 2010.

Recently, Bryan Caplan reviewed Gruber’s latest work, a graphic novel touting the virtues of PPACA. If Caplan’s description of the graphic novel is sound — having not read it, I can’t say — it raises questions for reporters and citizens inclined to take Gruber’s assessments at face value.
