I lived (past tense) in Fairfax county for more years than I care to count. I literally was losing my mind could not fucking stand it anymore and left in early 2017 ("it" being living in a liberal hell hole)
That decision to leave was up there with some of the best fucking decisions I ever made in my life.
That said, nah, most of the die hard liberal/democrat voters in Fairfax are not poor people looking for free shit. They are middle class to upper middle class, and they truly believe that the the Dems are saving the world with abortions, helping minorities battle evil white supremacy, and environmental issues.
Of the two dems I spoke 2 the day before the gov race (was curious if they woke up), one said abortion was the only issue she was concerned about AND she hates Trump, the other said, and believes to the core of his being, that Democrats are looking out for the little guy like him.
He also said to me that I am insane to think a democrat would literally believe any of the things that democrats say on the news every night that they stand for. For ex, he does not believe they want to defund police, he thinks that is not real. Pick your clearly stated on CNN insane Dem position, and he thinks that isn't real and won't really happen, its all just grand standing for attention, that is all.

There is just no fucking hope for some people and how they think.
Just 2 small examples of a 100 I could tell you from people I know that live in Fairfax and vote D no matter what. Not a single one was FSA
