I understand the importance of having a weighted system such as this or the electoral college in a general election when people across the entire political spectrum get to vote. Otherwise, every election would be decided by the leftist morons living in the big cities.

However, in a party election I don't see the need for this. Everyone voting is on the right. Sure some are more right than others, but I feel it should be based purely on votes. They can still do the ranking system....just have it based on number of votes across the country instead of points.
