Let me ask another question related to this. Is there a possibility one or both parties may not be decided until the convention? Especially, if the GOP mess that fezzy predicts comes true?
After scheduling and what I perceived as an overall media lean to establish nominees in a snap, I think if Feb5 leaves either race (but especially both races) still quite scrambled and uncertain there may be a strong swing the other way. As opposed to talking about somebody's momentum the discussion may dwell on how wide open it is and help keep it open.
But going all the way to the convention is hard to imagine. Would be interesting though.
