The Roberts Court is a cesspool of open corruption that works to legalize the same.
People like to describe John Roberts as an institutionalist a bit overwhelmed by how contentious his Court has become and how far and fast it has swung. Given his unwillingness to meaningfully address behavior that justifiably destroys public confidence in the Court, I don't think that's a fair description. Any "institutionalism" is eclipsed by… something else.
