The Democratic race is about to end.

Barring something truly extraordinary, Hillary Clinton will be declared the presumptive nominee for president by the news media, probably on Tuesday after the results in New Jersey. It will happen even if she loses every remaining contest, and it will probably happen before the polls even close in California (no doubt igniting the fury of some Bernie Sanders supporters).

How is she going to clinch?

Mrs. Clinton has 2,310 delegates, according to The Associated Press, putting her just 73 short of the 2,383 needed to win the nomination.

She will cover at least half the distance this weekend, when Puerto Rico and the Virgin Islands hold caucuses worth a combined 79 delegates.

She would then go over the top with New Jersey, not long after 8 p.m. on Tuesday, as Harry Enten at FiveThirtyEight has pointed out. The state is worth 142 delegates, and Mrs. Clinton will be awarded many of them when the polls close.
