Damn right. And from the biographical information I've read, Thurgood Marshall's faculties were pretty damn weak for the last 10 years or so of his tenure--and his "aides" pretty much did his thinking for him.
In fact, I would say a combined "flat line" brain wave from Scailia, Thomas, Roberts and Alito would STILL have about 5 to 10 times the intellectual capacity of Ruth Buzzi Ginsberg.
LOL! Or Andrea Martin's character from SCTV... Edith Prickly
