without the judgement that resulted from his decades of rubber-stamping nominees in the Senate, the jurisprudence and caselaw could have been radically different by the time Donald j Trump was in a position to nominate anyone. in fact, it's possible trump never would have been president if Biden had ever once in his life done the right thing.
