The Worry About List Candidates in MMP

Many who don't like the idea of MMP, don't for the main reason that they think that the List candidates are just going to be hand-picked by the party leader. But, why would the party leader do that if it isn't attractive to the voters? It stands to reason that the parties will pick their List candidates in a similar democratic fashion as they pick the local candidates.

Here is an excellent post from The Fifth Column about this.
"The law (and proposed law) is in fact no different as far as the selection of local and list candidates. It is up to the parties to use democratic selection methods and up to the voters to judge them on the methods they use."
