I wonder what proportion of coffee shop tip jars across the United States have some variation of “change we can believe in” as their witty plea for tips. I also wonder whether this proportion varies directly, inversely, or not at all with the strength of the Democratic party in the area (or amongst coffee goers in the area). But how do I get data to test this?
