Joe Biden has won the Democratic presidential primaries in Missouri and Mississippi.
Missouri has 68 delegates at stake. Mississippi has 36 pledged delegates at stake.
Missouri is among the more conservative of the six states holding Democratic primaries Tuesday. All but one of the statewide elected officials are Republicans. The Democratic presidential candidate faces an uphill battle to carry Missouri in November against President Donald Trump, who won the state by 19 percentage points in 2016.
Biden campaigned in Mississippi on Sunday, working to shore up support among African Americans, who make up 38% of Mississippi's population and an even larger share of the Democratic electorate. Sen. Bernie Sanders canceled a plan to appear Friday in Jackson so he could campaign in Michigan, which is also holding a primary Tuesday.
