If the Republican presidential field were any more unstable, it would be radioactive. At this point just about anyone can jump in and briefly poll on top of the heap, before slowly sinking down to the bottom again, like a banana in a bowl of stale jello. Party players pin their hopes on candidates that aren't running. Pilgrims in thousand dollar suits court state governors. Activists assemble petitions. But none of that is the solution. It's not so much that the man is missing, but the message.
