DETROIT (Reuters) - For David Green, head of the Detroit chapter of the Democratic Socialists of America (DSA), Donald Trump's victory in November was both distressing and cause for optimism in his quest to pull the Democratic Party to the left.

"We need a party that’s open to progressive forces, and that’s why we have to elect progressive leadership within the party," Green said, while attending the Michigan Democratic Party's spring convention in Detroit earlier this month.
