There is no shortage of Marxist leaning candidates available to the Dems. It is the plethora of Marxist leaning candidates that seem to be circling around the RNC that worries me. At the present rate RINOs will be considered to be 'right of center' in American politics.
Hillary needs at least one on the Far Laft (Rahm or Sanders), and whoever GOPe puts up will be played as a Far Right TEA Party Extremist so Hillary can triangulate toward the reasonable, rational center.
