Yes, we can. That's the perceived run-off effect.

That's a rather slavish devotion to unreliable probabilities. If 
those candidates turn out to be contenders, that means our 
probability assumptions were drastically wrong, and making strong 
statements based on faulty data is a strategically bad move. At that 
point, it would be more prudent (IMO) to vote as if you had zero 
information.
