As expected, Donald Trump easily won the Washington state primary on Tuesday, getting about 76% of the vote. Withdrawn candidates Ted Cruz, John Kasich and Ben Carson were also on the ballot.
Trump's win adds 40 delegates to his total, the state's other 4 delegates remain to be allocated. This brings him to 1,209 delegates, just 28 from the 1,237 needed to win the nomination. He is expected to cross the finish line at 8PM on June 7th, when he is declared the winner of the New Jersey primary and that state's 51 winner take all delegates.
June 7th is the next and final date on the Republican calendar. In addition to New Jersey, four other states will hold contests that day, with 303 total delegates.
