Bernie Sanders has won the US Democratic caucuses in Alaska and Washington by a huge margin, giving his campaign a boost against front-runner Hillary Clinton. He also won the preference poll in Hawaii.

He has done well in states with larger white populations and where caucuses are held, due to the outsized role liberal Democrats can play in those contests.
