Sanders is striking a populist note and like Trump is feeding on frustration and anger. And yet, he's not really advocating positions nor does he have the record that would indicate he's fully prepared to take on the system. He wants to remedy certain situations without acknowledging they are systemic. Trying to treat symptoms won't accomplish anything. The fact that he seems to advocate the whole Militaristic-Imperial system demonstrates that he either doesn't understand or is unwilling to truly take on the cancer that is the American system. You can't take on Capitalism while defending the Empire. They go together.
