Yes, they and everyone who understands how elections work know that it is completely irrelevant. If a large rural county has 100 voters voting Republican and a compact urban county has a million voters voting Democratic, the red area would be larger than the blue but the blue has more votes representing the more popular candidate. In this case, the map of the US is dominated by red because of the large land-are but small-population rural counties covering most of the landscape. Are you misunderstanding this on purpose or do you really not know how this works? Again as we know, Hillary had nearly 3 million more votes than Trump. This proves the amount of red is irrelevant. What matters is the states those votes are in.
