[EM] Did someone say monotonicity? Or: Droop proportionality and monotonicity

[Toby Pereira]

 I feel compelled to point out that proportionality is not the same as Droop proportionality. Something can fail one particular "brand" of proportionality and still be proportional.

 Dear Kristofer,

your argumentation basically is: When some voters rank X higher,
then it is not possible that some other candidate Y becomes a
member of a solid coalition.

My argument basically is: When some voters rank X higher,
then it can happen that some other candidate Y who couldn't
be elected without violating Droop proportionality can now
be elected without violating Droop proportionality.
(In example 3 of my paper "On Dummett's 'Quota Borda System'" ,
X=B and Y=E.) Candidate Y can then kick candidate X out of
the winning set.
