rich party problelm

[Mike Ositoff]

With Approval, or any other method, if voters want to optimize
the election result for themselves, a rich party could run lots
of really odious candidates, and if they have a chance to be
frontrunners with that party's moderates, and if the merit
difference is sufficiently great between abominables & moderates
then people could be given strategic motive to vote for that
party's moderates, and one of them could thereby gain election.

Not an Approval problem. Any method that has any lesser-of-2-evils
problem. VA doesn't have that problem. Approval has it some.
Margins has it worse than Approval. IRO has it worse than Margins.

But that isn't the rich parties problem. Rich parties is about
count rules that automatically give it to a party because
it adds candidates. Copeland & Dodgson are like that.
Approval doesn't have that problem.
