I tried to define term "competitive" in another mail to make the  
difference between polls and contentious elections (http:// 
lists.electorama.com/pipermail/election-methods-electorama.com/2006- 
October/018710.html).

I think there is a continuum between these two extremes. When  
discussing Pizza preferences competitiveness=0.1. When deciding which  
Pizza to buy competitiveness=0.4. When electing a president  
competitiveness=0.8. When deciding who gets eliminated from a 1M$  
competition in TV competitiveness=0.98.

Some election methods are robust enough so that competitiveness has  
no big impact on them (typically all vote sincerely or according to  
some basic well known strategy). Some election methods need low  
competitiveness levels to work. Some election methods may change  
their behaviour depending on the situation (the Ranked Preferences  
try to do this a bit - stronger preferences can be used also for  
defensive purposes - e.g. by voters who fear that the remaining  
strategic vulnerabilities of Condorcet might harm them).
