There have been yes/no polls about some suspects: Partrigde (a dozen of them), Bertram, McAllister - who is all of a sudden getting real popular based on a 30 sec promo.
Now, I would like to do one for Haffner, who I believe to be the one and only Red John. (I assume there didn't occur a poll for him yet, my bad if there was one before!)
Could be interesting to look back at after the final reveal ;)
GREEN: Haffner it is
RED: someone else
How do you find this theory?
plausible
unlikely
