Plural voting is the practice of allocating more than one vote to a person based on some criteria (such as land ownership, university education, etc...). According to Wikipedia, anywhere it was in existence has long abandoned the practice.
Is there anywhere in the world where plural voting is currently in effect for political elections?
Are there any notable proposals to implement plural voting in modern times aside from "parental vote" model listed on the Wikipedia page? ("notable" for me is defined fairly liberally. Let's say, more than 1,000 people signed on to support you, or more than 50,000 people are aware of the proposal. As opposed to a blog post read by 10 people).
