The author poses some very difficult questions that left-liberal activists have a lot of difficulty answering such as "how serious is she or any Green Party leaders to solve the myriad and profound problems of today's nation?" In contrast to this party that seems to offer political careerists many advantages and their supporters a "warm fuzzy feeling", the author points to the real dedicated activists.
It is not the case that everybody involved in political organizing in the US is simply looking for a warm fuzzy feeling when they go home at night. Rather, there are hundreds and thousands in cities like Ferguson and Baltimore and Anaheim and Salinas and Milwaukee and Oakland who have risen up against police violence. They are not looking for a good feeling, rather they are looking to protect their lives from state forces that want to kill them. They are not revolting out of inspiration over a Keynesian economic program or a promise to cancel their student loans, rather they are risking their lives and their livelihoods to construct a different world because they cannot survive in the one that they have been born into. They have nothing to lose but their chains.
