California is more complicated, with 172 delegates at stake. The statewide winner gets only 13. The other 159 are awarded according to the results in individual congressional districts.

Each of the state’s 53 congressional districts has three delegates. You win the district, you get all three.

For Trump to clinch the nomination on June 7 – the last day of the primary season – he has to win a big majority of California’s congressional districts. If he wins 39 districts, he gets 130 delegates.

On the last voting day of the primary campaign, we’ll say Trump wins 242 delegates.

Trump’s running total: 1,226 – or 11 delegates short of the magic number.
