That works out to be the same as the poisson proposal, in the limit as voter
number -> infinity and p -> 1. I think that the poisson proposal leads to
cleaner math. For instance, just for the sake of argument, imagine a system
where a margin of 1 counts as a tie and a coin is flipped. In this system,
with your proposal, a single vote might not be enough to increase the
expected value, because it is the only vote of its kind. However, with a
poisson distribution, 1 vote can turn into arbitrarily many (with a very low
probability).
