[EM] very simple email poll

[Forest W Simmons]

An observation on the ordinal version:

1 A>C>B
1 B>C>A

If the method is clone free and neutral, then the clone sets B'={A,C} 
and A'={B,C} must have equal probability with B and A respectively.  
This implies that C must have zero probability.

In the ratings version that Jobst specified in his simple poll, it 
would be a stretch to say that either {A,C} or {B,C} was a clone set, 
since their ratings are so distinct.

So I would think that a ratings method that gave some positive 
probability to C might still be considered "clone free."
