Americans hate politics and politicians, they hate the phoniness and the fake institutional seriousness of it, especially when it fails to have a real material impact on their lives.
So naturally, Democrats turned themselves into the most phony, Beltway brained creatures on earth, obsessed with the most trivial elite bullshit, rather than talk like normal human beings.
When people say Democrats have a messaging problem, it's true, and it's because the message and the messengers both suck.
