"Specter can redeem himself for Bork by supporting this."
No redeeming necessary. Bork was the opportunist at the heart of Nixon's "Saturday Night Massacre" firings of Archibald Cox and Eliot Richardson, and thus became involved in the coverup of the Watergate crimes.
He was a bad nominee, a silly looking man and corrupt. Specter stood with an overwhelming majority of Americans in opposing Bork.
From what I have learned since, I am glad that Bork was not approved, but I am sure that Specter didn't 'bork' Bork because he thought that he was doing the right thing by us. He took him down for his pro life views.
And what does his 'silly looks' have to do with judicial qualifications? You're better than that and only weakened your argument by mentioning it.
