I prefer Approval to ERIRV for the same reason I prefer it to ERBucklin:
These last two make it too easy for voters to make their vote useless just
by trying to take advantage of the ranked ballot's support for being fully
expressive.

I had a thought: Perhaps we could get more participants in a poll if the
subject was not political. I'm not interested in voting for candidates for
president, but I would submit a ballot if the subject were preferred flavors,
or celebrities.

It's much better in that I think there would not be so much nomination disincentive,
or order-reversal incentive.
It's going to be worse, from the perspective of people who think it's important
to find majority-strength coalitions, because of all the compression incentive.
It won't be possible to ensure that there is only one "majority winner."

Yes. But not for multiple winners of course.

No, I really don't see that. I think there is still too much pressure to dump
semi-viable candidates.
