Yes, as the person who patched together the final version of the amendment that established the executive, it was always intended to be a simple majority. What I have been puzzling over is can this be structured as a pair of bills, each establishing an ordering of a pair of candidates? Let [b:3vy9efup]A < B [/b:3vy9efup]mean that A is preferred over B.
[code:3vy9efup]if A < B:
if A < C:
A wins
else:
C wins
else:
if B < C:
B wins
else:
C wins[/code:3vy9efup]
In effect an tournament. In this way we satisfy the constitutional requirement, and fairly establish the preferred candidate of the three. The problem with this system though is that it can be broken by insincere voting.
One way to fix it, however, is to use the Borda counts. We could do the Borda counting to establish a winning candidate, the confirm that candidate through a majority vote.
