I took your comment to mean that the county level map is in some way meaningful or important. My point is that not only is it irrelevant, it is also deceptive.
Deceptive? It is what it is. It marks counties red that voted one way, and blue that voted another (with varying shades that reflect the margins of victory). In order to be deceived by it, one would have to misinterpret it. Yes, a person might assume that each bit of red has the same population density as each bit of blue. A state-level map could be misconstrued in exactly the same way, or to mean that everyone in the state of Virginia voted for the Democrat.
If you mean, by your first sentence, that you see no significance in the county-level map, then I'm sorry. Perhaps, with some reflection, you will.
