Democratic presidential candidate Vermont Senator Bernie Sanders won three western state caucuses on Saturday.

Sanders received 81.6 percent of the vote in Alaska, while his rival, former Secretary of State Hillary Clinton, took 18.4 percent, the AP reported.

Sanders won Washington state with 77 percent of the vote.

In Hawaii, Sanders took 70 percent of the vote to Clinton's 30 percent.

“We knew things were going to improve when we headed west,” Sanders told a crowd of jubilant supporters at a campaign rally in Madison, Wisconsin. “Last week we won Utah with 78 percent of the vote. We won Idaho with 79 percent of the vote.”

“[W]e have a path toward victory,” he said.

Sanders added that he and his wife's “family values” were very different from those of Republicans.

“What they mean is that our gay brothers and sisters should not have the right to marry. I disagree,” he told the cheering crowd.
