US 2016: Sanders wins Washington, Alaska and Hawaii

Bernie Sanders has swept to victory over Hillary Clinton in all three states that voted for the Democratic presidential nominee on Saturday.
The biggest prize was Washington State, but Mr Sanders also won in Alaska and Hawaii, boosting his campaign. He took at least 70% of the vote in all three states.
Mr Sanders thanked his supporters and said his “campaign has the momentum”, but he still faces a tough task to overhaul Mrs Clinton.
After Saturday’s caucuses, she leads Mr Sanders by 1,243 delegates to 975, the Associated Press count shows.
When superdelegates – party officials who can support either candidate – who have so far declared their allegiance are included, Mrs Clinton is ahead by 1,712 to 1,004 in the race to reach 2,383 delegates.
