The Democratic party - at least in my state - isn't fighting for free public education like they should. They're always coming up with plans for improvement that involve top-down solutions that serve already privileged populations, and avoiding sweeping bottom-up measures like more funding in general, better professional conditions for teachers, etc. A lot of the problems in education could be solved with more money, and nobody ever wants to argue just putting more money into schools. All the plans are how to shuffle things around, or new administrative processes, or new testing processes, when it's really just a matter of raw resources.
