When you instead match up personnel and voter registration records you get that about half of the federal workforce was Democrats. Republicans were around a third in the late 1990s, but fell to about a quarter by 2019.

Polls of federal workers for specific elections also suggest that it is not nearly as imbalanced as the money totals. For instance in the 2022 midterms 37% of federal workers said they were voting Democrat in Senate races and 33% said they were voting Republican. In House races it 46% voting Democrat, 35% voting Republican.
