I don't think this argument will get Range very far since without the
assumption of sincerity, it only satisfies "voted" IIA and could still be
affected by "sponsoring rival candidates."

I also think you would need to describe the issue in a less absurd-sounding
way. I don't think much of anyone is alarmed about the appeal to parties of
"sponsoring rival candidates" under any method, let alone ALL methods.

And while you'd be discussing this, the lawyers on the other side would be
pointing out that Range can fail to elect the voted first preference of a
majority. This issue would be a significant hurdle, do you agree?
