Bernie Sanders as mayor of Burlington, Vermont

"At the same time, critics on the left said he compromised too much with business interests and did not go far enough in pursuing socialist ideals. Over the span of his mayoralty, the number of families living in poverty grew — to 798 in 1990 from 563 in 1980, an increase of 42 percent....Mr. Sanders also formed alliances of convenience, including one with Antonio Pomerleau, a wealthy developer whom Mr. Sanders had criticized during his first campaign for mayor."
