"In your estimation, approximately what percentage of the ruling
   class " I can answer. "has no genuine belief in God, but " I
   can't answer. I can't know the genuineness of someone's beliefs
   or not. "portrays themselves as religious in a deliberate
   attempt to garner the support" I can answer. "of the religious
   portion of the public, and to perpetuate religion as a system of
   control?" I can't answer because: a) I don't know if they are
   targeting specifically the religious portion of the public. b) I
   don't know if their purpose is to perpetuate religion as a
   system of control. c) I don't really understand what "religion
   as a system of control" is supposed to mean. So, I can answer
   this: "In your estimation, approximately what percentage of the
   ruling class [...] portrays themselves as religious in a
   deliberate attempt to garner the support [...] of the public?"
   As politicians are actors and always "on", 100%, I believe that
   we can never know what they really believe about anything. I
   don't know how much they believe what they say. I don't know how
   much they're saying thing to get _us_ to believe. But
   "portraying" is key. Politicians portray [something]. Whose
   support are they trying to get? Religious and non-religious
   alike. Even people who are non-religious (who aren't
   anti-religion, just non-religious) might see a religious person
   as potentially more stable of a personality.
