The ideal way to sort out this concern would be have the reweighting be
1 instead of 0.  However, having a reweighting of 1 means that a faction
could get a turkey candidate into the second round, as Chris has pointed
out.  The compromise between a reweighting of 0 and 1 is 1/2!
Personally, I agree with dropping rule #2 but would keep the reweighting
at 1/2.

Thanks,
Gervase.
