Hillary Clinton took more delegates out of the primaries in Michigan and Mississippi on Tuesday night. But Bernie Sanders, by winning in Michigan, scored a massively important symbolic victory that will likely reenergize his campaign and extend the Democratic presidential race for weeks, if not months.

“What tonight means is that the Bernie Sanders campaign ... is strong in every part of the country," Sanders said in brief remarks in Florida on Tuesday night. “We believe our strongest areas are yet to happen."
