President Donald Trump and Democratic challenger Joe Biden won’t face each other directly in Tuesday’s presidential primaries.

But voting in Georgia and West Virginia give both campaigns an opportunity to prove they can assemble a coalition strong enough to win in November. The primary contests follow a week of massive protests against police brutality that energized the African American community and its white allies. 

It’s an open question, however, whether the energy on the streets will translate into energy in the voting booth. Georgia is also holding a Senate primary on Tuesday, with congressional primaries in states including Nevada and South Carolina.
