Well to paraphrase that old senator Roman L. Hruska, R-NE, “even corpses need a little representation too.” I think he said that in 1970 when Judge Carswell, a Supreme Court nominee, was called “mediocre”, and Hruska said even the “mediocre need representation.”
Given how Roberts was able to outsmart himself on Osamacare I’m thinking Hruska was right, we could do with a mediocre SC Justice as long as he was a conservative.
