There are certain limits imposed by hammering on a cellphone screen into a microblogging platform. You're not going to get a nuanced manifesto here. That said Dem leadership had been far too concerned with wooing "moderates", suppressing base turnout and allowing truly awful policy to pass.
The shallowness and lack of thought and reason in the "Democrats are complicit" pronouncements are not attributable to limitations of typing on a cellphone. And there's plenty of room between a "nuanced manifesto" and the fact-free, buzzword-laden accusations you're throwing around here.
What are they doing, then?
There are plenty of sources you can consult to educate yourself. I suggest you do some research.
I have. IMO so far it supports my thesis. Back up your claims.
