Jim Rader - Bernie Sanders

Senator Bernie Sanders was until recently probably best known for being one of the few self-described socialists to be voted into public office in the United States: first as the mayor of Burlington, Vermont in 1981, followed by a stint in Congress and then the Senate. More recently he's been attracting massive crowds in his campaign to become the Democratic presidential candidate. Jim Rader, who's known Sanders since the early 1960s, reflects on Sanders' politics and beliefs.
