Toomey would have voted the right way as a regular habit. Someone else could have been appointed to the Judiciary Committee who would have done the same thing or better than Specter on appointments.
Jon Kyl was on that committee too and he could have stepped up into the Chairmanship and later Ranking Member. In fact, Jeff Sessions (who is also excellent) did move up into that position. Both of them would have been a thousand times better than Specter.
Still, Santorum has been a great senator and I thank him for his valuable service--especially to the unborn.
