Sorry, but this doesn't scan. "The concerns of rural communities" are overrepresented in American politics. Twenty percent of the population is represented by the Senate majority and are able to, at minimum, gridlock the American system of government (and, at maximum--well, quite a lot, given SCOTUS and what we've seen over the last few months).

This is, of course, an intentional behavior of our system of government. You can even make an argument that it's a positive one. (I would disagree.) It is not, however, "democratic", nor does it point at some kind of underrepresentation.
