Behave, Arlen:

A Pittsburgh Post-Gazette interview with GOP Sen. Rick Santorum generated the most significant comment so far from the junior Pennsylvania senator about liberal Republican Sen. Arlen Specter’s rise to the Judiciary chairmanship. “I still believe I did the right thing [in backing him],” said Santorum. “I know how he’s going to behave as chairman of the Judiciary Committee. I have a lot of confidence he’s going to be fair.” During Specter’s tough 2004 primary fight with then-Rep. Pat Toomey, Santorum sided with his Senate colleague, who won a narrow victory. Then, in November, Santorum stood by Specter after he suggested President Bush might have a difficult time getting pro-life judges confirmed.
