Michigan Primary Look Ahead Katherine Gypson WASHINGTON - In 2016, Michigan gave Sen. Bernie Sanders one of the most surprising primary wins in U.S. political history. In 2020, the self-described democratic socialist will need another boost from Michigan to revive his campaign to secure the Democratic presidential nomination over his lone remaining major rival, former Vice President Joe Biden. With 125 delegates, Michigan is the biggest prize up for grabs among the six states holding primaries Tuesday. Sanders signaled the importance of Michigan to his campaign, abandoning a planned rally in Mississippi to hold five campaign events in the state over the weekend, including one in Dearborn, where the nation's largest Muslim community strongly supports him. Dearborn was one of the areas that helped Sanders secure his 2016 victory in the Michigan primary over eventual Democratic party nominee Hillary Clinton by a narrow margin of 49.8% to 48.3%. After trailing Clinton significantly in the polls, Sanders won by just 17,000 votes. Sanders aims to improve on that narrow margin of victory in 2020, even though in some states to date, he has struggled to turn out voters in the same numbers he did in 2016.A Detroit Free Press poll released Monday does not look promising for him. The survey of 400 Michigan voters shows Biden outpacing Sanders by a significant margin -- 51% to 27%. "If Bernie doesn't score a big victory in Michigan, you're really starting to see the end of the possibility of his candidacy," said Jim Kessler, a senior vice president at public policy think tank Third Way, and former legislative director for then-Congressman Charles Schumer.
