For me...that is the signal from the White House to let him be.
I can only deduce that they've made some quid pro quo deals concerning Specter's election and W's nominees.
I'll now hold my fire. Once we merge with the enemy on the nominees I'll watch for Specter's activity. If at that point he gets in the way, the White House will turn on him and I'll get back to going after him.
For now it is clear, the White House will obliquely support him...therefore I cease fire.
Oh brother...maybe you can get this thread pulled too and destroy the evidence.
