It is so clear to me now. Castle is not running. The moment that announcement is made Protack will announce that he is running in a primary against O’Donnell. Rather than run into a wall of incoherent wingnut rage, Copeland will sit out and hope for the GOP to right itself in time for 2012.
In a DE GOP primary race that will break all records for bile, stupidity, and lackluster fundraising, O’Donnell will win with a vote tally of something like 375 to 310.
Then O’Donnell will be crushed by Beau Biden. I think this is why Castle is not saying anything. He can see the future as clearly as I can.
