Regarding your NRO piece on Justice Thomasโ€™ experience with Biden, this sentence by the inexperienced Clarence Thomas of 1991 struck me: โ€œBut I donโ€™t believe that in my writings I have indicated that we should have an activist Supreme Court or that we should have any form of activism on the Supreme Court.โ€
Hmmm, โ€โ€ฆin my writingsโ€. Where do we go to consult Barack Obamaโ€™s writings on such weighty constitutional law questions? Perhaps one of his old students has a class notebook with the good professorโ€™s thoughts recorded.
