With all due respect to all involved I read his comment as geographic population density. I've lived in voting districts where the election was in the basement of my dorm, in the suburban subdivision's elementary school, and in a rural area where voting was a good 10 minute highway drive. Obviously theres a big difference in "get out the vote" when one voter is pound on the dorm door and tell them to press the "B" button in the elevator, than some rural district where each voter represents like a quart of gasoline burned.
