On the contrary, at least 50% of the votes always matter. It's really simple if you think about it.
I understand the point you think you are making about the necessity of a majority-winner election to have greater than 50% of the votes cast be towards a singular candidate. However, losing votes and votes in excess of the number needed to win given the vote allocation
(maybe that helps?) are votes that don't matter.
We're holding a silent auction, and whoever bids the most wins. I have $60 on me; you have $40 on you. I write down $41 dollars as my bid on a mint condition Barack Obama trading card and half-eaten ham sandwich. Do you bother to bid $40? Do I bother to bid my remaining $19? No. I would need $51 of the $100 between us
to guaranty I win, but I only need $41 of the $60 I have
to win. None of our other dollars can affect the outcome of the auction. Edited, Dec 20th 2017 7:29pm by Allegory
