Corporations fund the big name democrats and their campaigns. These same corporations benefit greatly from Republican wins. They are buying intentionally ineffective democrats who are unincentivized to either win races or appeal to worker interests as they are typically directly at odds with these big bankrolling corporations.

I am not saying every democrat is paid for or every democrat is ineffective or democrats as a whole are an entirely bought and paid for organization, but what I am saying is that enough of the prominent enough democrats legitimately are financially disincentivized from helping the people they’re supposed to represent so as to effectively gum up the works of the whole machine.
