[EM] Re: IRV vs. Runoff

Chris:

The definition is given on page 4:

"The majority rule selects the plurality winner if she
receives a score larger than n/2,
which means that more than half of the electorate puts
her on rank 1."
<http://www.econ.kuleuven.ac.be/ew/admin/Publications/DPS99/Dps9911.pdf>


Apparently, that is a rule where there is sometimes no
winner (just as is the case in the election of the
Pope, which requires a 2/3 majority). If somebody gets
more that 1/2 of the first preferences, that is the
majority winner. Otherwise, there is no majority
winner. Both the majority rule and the 2/3
super-majority rule may be more commonly used as
parliamentary procedure rules, but they are used for
elections, too.

Anyway, I would really like to know your opinion of my
resolution. Are my Whereas clauses true, or not? Is
the argument sound?

Did you know there is an web site where, if you click on a button, the advertisers there will donate 2 1/2 cups of food to feed hungry people in places where there is a lot of starvation? Consider making it your home page. See:
