The politicians are the symptom. The voters are the disease. They've been shaped by Marxist indoctrination since they were 5 years old, and most of them are unwilling or unable to analyze the policies of the Democrat party to see just how poisonous they are.
Most of the Democrat base are so mired in hatred of capitalism (like they even know what it is) and envious of the successful (I just graduated with a degree in ----Studies. I should immediately get a six figure salary for working a 5 hour day) that they never think that maybe it's their own attitudes and bone deep ignorance that are represented by who they vote for that cause their dissatisfaction.
