With 2/3 of the voters agreed they will vote left, they could have made out 
much better with Condorcet.  Even if all voted the indicated first choice 
it would not have taken many second choice Jospin votes for him to win. 
Some others also were possibilities with Condorcet.

Debatable whether a runoff would have been appropriate with Condorcet. 
Unlike Plurality, it permits voters to more completely express their desires.
