The concept when used in past elections would get a lot of people the results they want, but if they actually put that system in place instead of working towards middle ground it would actually push the ballot to the extreams (not a bad thing in my opinion). The end result wouldn't be much different then the end result we get now. For example if this system was in place in 2012 Mitt Romney would make sure Ron Paul also was on the ballot, Obama would have to find a high profile Green candidate, and some moron like Michael Bloomberg would think he had a chance and take 4% of the vote at random. In the end it would be a close race between the highest profile best funded Republican and Democrat endorsed candidate. Every once in a while a Ross Perot type could have a chance, but that candidate would have to be flawless and get lucky on election day.
