Lorrie Cranor's Example

[New Democracy]

Greetings,

Below is one example from Lorrie Cranor's paper on the net via Rob L.

    voter 1: a b c d e
    voter 2: b c e d a
    voter 3: e a b c d
    voter 4: a b d e c
    voter 5: b d c a e

I noticed that two candidates have zero votes in the first set of selections.

My question is: How is this handle when pairing? Do you still include these
two candidates in all the possible pairs? Would it be possible for a zero
candidate to maybe win the election in a different Condorcet example?

I am curious.

Donald,
