President Joe Biden won the South Carolina Democratic primary with 96.4% of the vote and claimed all 55 state delegates.

Biden's support among black voters in South Carolina has halved from 86% to around 50% over three years.

Primary challenger Rep. Dean Phillips criticized Biden's leadership but secured less than 2% of the South Carolina vote.

Despite a successful campaign to mobilize Black voters in South Carolina, overall low voter turnout raises concerns about Biden's re-election prospects.

Biden is now campaigning in Nevada, facing unpredictable results in a state with a transient, working-class, and diverse population.

The Democratic National Committee is investing in Nevada to encourage minority voter turnout, while Biden emphasizes the threat posed by Trump and his own economic achievements.

Biden's campaign strategy includes focusing on holding Nevada and energizing the Democratic base in upcoming primaries in Nevada, Michigan, and 'super Tuesday'.
