Suppose the system were CW, and the preferences were as follows

40%  Gore>Nader>Bush>Buchanan
20%  Nader>Gore>Bush>Buchanan
10%  Bush>Nader>Buchanan>Gore
20%  Bush>Buchanan>Nader>Gore
5%   Bush>Gore>Buchanan>Nader
5%   Buchanan>Bush>Nader>Gore

Nader beats Gore 55% to 45% .
Nader beats Bush 60% to 40%
Nader beats Buchanan 70% to 30%

D- What happens on a YES/NO vote for each choice ??? -- since rankings are 
*relative* and NOT absolute.

Do ANY of the choices get majority acceptability (especially Mr. Nader or Mr. 
Buchanan) ???

The actual plurality results were roughly Gore 49, Bush 48, Others 3.

The obvious left-right spectrum is
Nader - Gore - Bush - Buchanan.
