No sooner had Sen. Arlen Specter (R.-Pa.) emerged victorious in his fight to salvage the chairmanship of the Senate Judiciary Committee than he found himself facing a new enemy: Hodgkin’s disease. Specter announced this week he was diagnosed with Hodskin’s, a cancer of the lymph system. “I have beaten a brain tumor, bypass heart surgery and many tough political opponents,” he said. “I’m going to beat this, too. I have a lot more work to do for Pennsylvania and America.” Specter said he would continue to serve as Judiciary chairman. The venerable liberal Republican won re-election to his fifth term in November.
