There are certainly a lot of places where Democrats have fallen short but, in the big picture, Democrats are far less hostile to average Americans than the Republicans.

The worse the Republicans get, the more people want to see the Democrats as the “good guys”. That has unfortunately not been validated by Democratic policy most of the time. They do try to cater to average Americans, but only in ways that are palatable to the donor class. Republicans offer nothing to average Americans and rely entirely on culture war nonsense for popular support.
