Mad at Zell
Instead of focusing on what Miller said and the significance of his willingness to savage the titular head of his own party, they tried to explain away his behavior or get inside Miller's head about why he would turn on his own party.

They were trying to rationalize it, rather than present it as something the Democrats should take to heart.
Meanwhile, John McCain keeps folks wondering which side he's on in his continuing attempt at being relevant in today's political arena.
