He is an exceptional political activist and person, with a very clear, consistent message since the early 1960s about the importance of challenging the 1% on the behalf of the needs of the 99%. He been one of the few politicians to consistently work for the 99% and to address the problems of class warfare. Sadly, he's not appropriately strategic and has thus limited his political capabilities. He's not networked appropriately, and his activisim has extended to unworkable options, like cancelling student debt, approaches to 'socialist' reforms, remaining an independent, anti-NRA approaches, banking reform, opposition to the military industrial complex, to the Patriot Act, and reducing trade with China. All of these would be wonderful to address, but he should know how to work in increments toward those goals, rather than assume that there is sufficient political support for them. Nor has he had the necessary network of support. Politicians have to work with much greater complexity, rather than assume that a socialist revolution is possible on the Hill. He is however one of the best political activists for the 99%.
