Biden and Trump hope to add enough delegates in this Tuesday's primaries to be nominated by their parties. The Democratic president and the former Republican president do not face significant opposition in the primaries in Georgia, Washington, Mississippi and Hawaii.
The only question is whether they will reach the necessary delegates in each state to win the nomination. There are 254 Democratic delegates for Georgia, Mississippi, Washington and Hawaii, in addition to the party contests for the Northern Mariana Islands and Abroad that conclude Tuesday.
