The lower classes have never been represented in any government with a two party system. Such governments serve only their oligarchs and the technicians/tradesmen oligarchs depend upon to make the machines run. In an economy that is based in financial markets, not actual machinery, the bankers and brokers replace the tradesmen.
I completely share your revulsion and disgust for both DINOS, but mine extends to the entire Democratic party that sold out the working middle class decades ago. It is hard to justify objection to Republican tactics in general elections while defending Democratic leadership for their betrayal of their constituents in primary elections. Both are integral to our democratic process and require constant oversight.
