Mr. Simmons wrote- 

Here's why the 50% figure seems natural to me.  Suppose that there are
only two candidates. If neither one of them gets 50% approval, that means
that neither one could get 50% of the vote in a two way contest. Sounds
like a pretty lousy choice to me.

D-  I bring up (again) one of my standard divided majority examples--

Sincere first choice votes

26 A
25 B
49 Z
100

A and B have some sort of major connection.

Who makes second choice votes if there is no majority requirement ???
