You're confusing the discussion by trying to force the "leader" terminology. That term does not appear in the BTC whitepaper and the protocol's approach to consensus is different than a traditional leader elected system.
There is no "voting" and no "leader" except in the most abstract sense and I'm not sure why you're so determined to use those terms.
