HotAir: Ed Morrissey: Sestak Goes Silent

What’s going on with the Sestak quietude? Ed muses:
“Now the same party leaders whine to Politico that Sestak hasn’t called to get them on his side. Well, perhaps he’s waiting for some apologies, from both the party leaders and from the White House, which are pretty clearly in order.”
What if Sestak just doesn’t want to answer questions? What if the answers get everyone in trouble? What if he’s been threatened?
It might not be the ghost of Arlen’s past. It might not be sour grapes. It might just be plain old paralysis in the face of a mean government machine.
