Haley took 63% of the GOP primary vote to 33% for Trump. Just over 2,000 D.C. Republicans cast ballots. Because Haley got more than half of the vote, she came away with the district’s 19 delegates.
Washington’s moderate set of Republicans, many of whom work in politics or government, are seen as vastly different than those in other early states like South Carolina and Iowa, which set up a scenario where Haley had her first legitimate chance of notching a victory. Trump got just 14% of the vote in Washington’s 2016 primary.
