I’d note that the Washington DC vote totals mainly reflect people who live in the District proper, most of whom are not federal civil servants. Plenty of those seem to live in the Virginia and Maryland suburbs, or closer to their federal workplaces in other parts of the United States.
Something tells me presidential vote totals around Fort Bragg or Oak Ridge—both home to notable numbers of career federal employees—might give a different impression.
