Well, since no one else is jumping in, let me see if I can prime the pump. I predict Kerry will be the next to drop out, perhaps even before the NH primary. Doing so at that point would permit him to avoid humiliation in his backyard state.
I think pretty soon it will dawn on Kerry, and that his friends and advisors will tell him, that he has no chance, and that he has already sacrificed much of his dignity. Time to end the bleeding.
