I don't know of one, but I think other states have discussed it. And, what is almost the same argument, is the question of winner-take-all or allocated delegates to the Republican and Dim conventions. I think a state or two does divide their convention delegates based on the number of votes primary candidates receive.
And, really, maybe those advocating this harebrained scheme would also like to have all convention delegates assigned to the primary candidate who won the most popular votes nationally. Same thing. There is some weighting in the number of delegates a state gets.
