The majority of Americans now think that presidential candidates should release their medical records. These demands for greater transparency are not unreasonable. The public deserves a basic understanding of candidates’ health. But as is often the case in medicine, the question is not whether, in some cases, a prescription could help. It’s whether, all things considered, the benefits outweigh the risks. In this case, a wholesale release of medical records would do more harm than good. Pundits and campaign operatives dissecting years of medical records would be only more fodder for political theater.
