Education has a left leaning bias, in spite of some prime examples to the contrary in this thread (it's statistics, after all, and not about particular individuals). So given that to become a federal employee (rather than, say, an elected official) you need to have some education and some skills it should be no surprise that they would skew left leaning as well. If there is an argument to be made that the 'deep state' exists and is democratic leaning that would be the one. But it isn't a bad thing and has - until recently - kept the USA from devolving even faster. But now the brakes are off and the train is gaining momentum. Whether it is too late to stop it or not I do not know.

There is an interesting concept in chemistry: activation energy. If there is a fuel/oxidizer mixture it takes a certain amount of energy to get the chain reaction started. Too little and the proto-fire will burn out by itself. But pass the threshold and it will continue to blaze until there is nothing left to burn. There is a good chance that we have passed the threshold as a society even though the fire has really only properly begun to burn a few months ago. Maybe it is not too late. But I wouldn't bet on that, too many people are spoiling for a fight, they'd harm their own interests happily if they believed it harms the other guy more.
