My only issue with this comment is that it seems to discount the idea of "unfairness" in our elections. Yes, in a federal election the districts don't matter. However, as we can see right now, the state legislatures that are elected via those districts can drastically change the landscape of a federal election within their state. The republican legislatures are moving en masse to "prevent fraud" in a way that seems to be directly aimed at making it more difficult to vote[1]. Appealing to more voters is hard when fewer people are able to vote.
