Wednesday;June 15, 2016:Last Democratic primary election has won by Hillary Clinton , which held in the US capital, formally wrapping up a long and brutal slog to secure votes for the party's nomination.

The win over Bernie Sanders was mostly symbolic, as the former top diplomat last week secured the number of delegates needed to become the Democratic nominee for president when the party holds its convention in Philadelphia next month.

Clinton won 78.7 % of the vote in Washington, as per the early results last night, with nearly 65 % of the votes counted.
