Joe Biden and Donald Trump hope to clinch their parties’ presidential nominations with dominant victories in a slate of state primaries on Tuesday as the 2024 fight for the White House moves into a new phase.

The only question is whether they will earn the necessary delegates in each state to hit the 50% national threshold to become their parties’ presumptive nominees.
