Serious question, then why do you keep doing it? You have to understand that constantly voting for the same shit, without doing anything to change who you're voting for or demanding anything of your leaders, was going to lead to the party becoming out of touch with your needs and wants right?
So, the electoral process has failed you every time that you've interacted with it, and you've watched as everything got worse these past few decades, but still hold faith in the process? Again, I have to wonder why? It seems like you'd be very justified in looking at the DNC as traitors, especially considering they personally gatekept some of your choices from the general election.
