The attitude to the presidential campaign of long-time independent US senator and self-proclaimed socialist Bernie Sanders has become a major debate on the US left. Some see his decision to run as a Democrat as the major dividing line, accusing him of sidetracking the left into support for the capitalist Democratic Party. Others, while recognising Sanders' shortcomings, point to the wider role his campaign can offer in providing a more radical pole of attraction in US politics at a time when the left is weak. Below Links International Journal of Socialist Renewal makes available two views from significant sections of the US socialist left. Readers' comments are encouraged in the comments box after the articles.
