Seattle : Bernie Sanders won decisive victories in Democratic caucuses in Alaska and Washington on Saturday, giving his campaign a much-needed boost as he seeks to disrupt Hillary Clinton's path to the party's presidential nomination.
US networks projected Sanders winning by wide margins in both western states where 117 delegates were up for grabs -- 101 in Washington and 16 in Alaska.
The Vermont senator and the former secretary of state were also facing off Saturday in Hawaii, where 25 delegates are at stake. The results for that contest, where Sanders was also favored to win, were expected later in the evening.
He celebrated his victory via Twitter late Saturday.
"Thank you, Alaska! Together we are sending a message that this government belongs to all of us," he wrote.
"Washington, thank you for your huge support! It is hard for anybody to deny that our campaign has the momentum."
With victory expected in all three of Saturday's contests, Sanders turned his attention to theelection contests ahead.
Appearing at a campaign rally in the midwestern state of Wisconsin, the Vermont senator said, after recent election defeats to Clinton, that the tide now is turning in his favor.
"We knew things were going to improve as we headed west," he said to cheers.
"We are making significant inroads in Secretary Clinton's lead and we have ... a path toward victory."
US networks projected Sanders winning 79.2 percent against 20.8 percent for Clinton in Alaska.
In Washington, he was projected to win 72.1 percent against 27.7 for Clinton.
"This is what momentum is about," Sanders told supporters in Wisconsin. "Don't let anybody tell you we can't win the nomination or win the general election. We're going to do both of those things."
A win for the 74-year-old Sanders in the trio of western states would inject momentum to his campaign as he seeks to dent Clinton's lead in the race to their party's nomination.
Going into Saturday, Clinton had already amassed 1,711 delegates, including super-delegates who are unelected by voters, compared to 952 for Sanders, according to a CNN count.
To win the Democratic nomination at the July convention in Philadelphia, 2,383 delegates are needed.
