It is difficult to determine which systems or any system at all would be most efective in the electorial process.The effects of the activities of parties are surrounded by an even higher level of uncertainy than those of other organizations.The only test effectiveness is whether or not a party wins office.It really has no effect on which party wins as long as there is another viable competitor the process is moot.Because it can always go either way the opponent only wins because of their decisions if they were to make different ones the outcome would be different.
