[EM] Margins

[Dave Ketchum]

PLEASE stick to the issue!!!

Recently you claimed that WV and Margins are identical, so my last 
iteration here quoted YOUR ASSERTION that they are different, as I have 
been claiming.

As to whether counting equality matters under Margins, we seem agreed that 
it does not.

What you imply is not quite true:
      Since Margins is in the business OF MARGINS, it cares not whether 
half-votes were counted, since they do not affect this detail.
      BUT what is significant is that counting half-votes DOES affect the 
numbers used by WV, where they therefore make a difference.

What you say about Margins is true - BUT talking about this side issue 
distracts from agreeing or disagreeing as to whether there is a difference 
between WV and Margins.
