tbf Biden made huge missteps in how he handled that. Look into it some (or read this New Yorker article, which I found looking up the Bork confirmation hearing). and he deserves a lot of shame for it and frankly he never should have been the option we are presented with. that so few people care about how Anita Hill was treated is ridiculous.
but it is not as if Biden supported Thomas. he fuged up in how he handled the confirmation process IMO as the investigation may have destroyed Thomas' chances.
