If cattle ranchers know there there is a public good for having wolves, yet they argue against them, I'm saying that position is a conflict of interest between them and the public good. They will almost always choose their own self interest. Voting? Well, people often vote against their own self interest, but it is hoped (by me, at least) that people will vote for their self interest, within reason. That reason is that you aren't voting for something that benefits your group more than another group. That would be a bad use of self-interested voting. A good use would be voting for "medicare for all" because you think it will benefit you and others.
