Bernie Sanders defeated Hillary Clinton by massive margins in the Democratic caucuses in Alaska, Hawaii, and Washington State on Saturday.

Sanders’ biggest win of the day was in Washington State where 101 delegates where at stake including superdelegates.

During a campaign rally in Madison, Wisconsin, Sanders said, “We knew things were going to improve as we headed west,” citing his wins in Idaho and Utah.

“We are making significant inroads in Secretary Clinton’s lead — and with your support here, we have a path toward victory,” Sanders claimed.

Heading into Saturday’s contests, Clinton leads Sanders 1,223 to 920 in the delegate count. However, when the superdelegates are accounted for, Clinton’s lead balloons to 1,692-949 over Sanders.

With 100 percent of precincts reporting in the Alaska caucuses, Sanders received 80.7 percent of the vote to Clinton’s 19.3 percent. Excluding superdelegates, Sanders will take home 13 pledged delegates, and Clinton three.

In Hawaii, Sanders defeated Clinton 69.8 percent to 30 percent. With 25 pledged delegates at stake, Sanders received 17 and Clinton eight.

Washington State was another big victory for Sanders, where he wrapped up 72.7 percent of the vote to Clinton’s 27.1 percent. Sanders received 25 delegates, Clinton nine. The rest 76 remaining delegates from Washington State are superdelegates.

Despite massive victories for Sanders on Saturday, Clinton retains her lead in delegates 1,712 to 1,004, mostly due to superdelegates. Counting only the pledged delegates, Clinton is beating Sanders 1,243 to 975.

The next primary election for both the Democrats and the Republicans will be April 5 in Wisconsin.
