Just in time for Christmas, the RNC has a gift for political junkies: a comprehensive document* that explains how each state (and territory) will award its delegates through the Republican presidential primaries and caucuses. 

It’s more than a little complicated, but it’s important because winning delegates–not states, not the popular vote–is what ultimately matters. The GOP nominee will be the person who gets the votes of 1,144 delegates (that’s 50% +1 of the total number of delegates) at the Republican National Convention in Tampa next August.
