Ron Paul Either Did Or Didn't Endorse Jill Stein

I don't actually care, because the number of people who would either vote for Ron Paul or Jill Stein would be able to hold a convention in an elementary school auditorium and still have room for a choir. But it's amazing to me that Ron Paul shouts out Jill Stein. I really did not know they had any significant ideological overlap. Actually, I'm pretty sure they don't. This is basically like taking protest voting to the nth, right?
