An interesting hypothesis from Ezekiel Emanuel and Theodore Ruger in today’s New York Times:
Obviously there are other considerations that may have motivated the ruling from Chief Justice Roberts, like not wanting his court to be tarred with another very controversial, politicized decision, but we should not overlook the role his health might have played.
Chief Justice Roberts has a pre-existing condition but is just 57, and thus not eligible for Medicare. Remember his unexplained seizure soon after he became chief justice? If he did not have employer-provided insurance and had to get his own coverage on the individual market, he would be denied health insurance coverage at almost any price. Maybe the appreciation for his precarious insurance status made Chief Justice Roberts more sensitive to the need for the Affordable Care Act and its requirement that insurance be available to all of those with pre-existing conditions.
