Biden Defeats Sanders in 3 Democratic Presidential Contests Ken Bredemeier WASHINGTON - Former U.S. Vice President Joe Biden swept to victories Tuesday over Vermont Sen. Bernie Sanders in the Democratic presidential nominating contests in three states, including pivotal Michigan in the Midwest heartland of the country. Biden, in his third run for the presidency over three decades, increased his lead in the race to oppose Republican President Donald Trump in November's national election with the wins in the U.S. auto manufacturing hub of Michigan, along with victories in Missouri in the Midwest and Mississippi in the South. The three victories could set the stage for possible Biden wins in three other states that voted Tuesday in the latest in a string of Democratic party primaries. The Biden victories make it ever more difficult for Sanders, a self-declared democratic socialist, to overtake him for the party's presidential nomination. .
