Fresh off a huge victory in Wisconsin, Sen. Bernie SandersBernie SandersWarren to protest with striking Chicago teachers Sanders: 'Outrageous' to suggest Gabbard 'is a foreign asset' Democratic strategist: Sanders seeking distance from Warren could 'backfire' MORE on Tuesday night highlighted the momentum his presidential campaign has been gaining over recent weeks.

Before getting into his stump speech at a rally in Laramie, Wyo., Sanders thanked voters in the Badger State for delivering him a significant win over Democratic front-runner Hillary ClintonHillary Diane Rodham ClintonSanders: 'Outrageous' to suggest Gabbard 'is a foreign asset' Clinton attacks on Gabbard become flashpoint in presidential race Saagar Enjeti: Clinton remarks on Gabbard 'shows just how deep the rot in our system goes' MORE.

“With our victory tonight in Wisconsin, we have now won seven out of eight of the last caucuses and primaries,” he said, factoring in his win among Democrats abroad. “We have won almost all of them with overwhelming, landslide numbers.”

The Vermont senator pointed to recent polls that show him in a dead heat nationally with Clinton or outperforming GOP front-runner Donald TrumpDonald John TrumpTrump says he doesn't want NYT in the White House Veterans group backs lawsuits to halt Trump's use of military funding for border wall Schiff punches back after GOP censure resolution fails MORE in general election match-ups.

He's hoping the recent momentum will translate into more superdelegates, who are free to support whichever candidate regardless of who wins their state, flocking to his campaign.

"I think a lot of these superdelegates are going to be saying which candidate has the momentum, which one brings out huge numbers," Sanders said.

While some have recently started to shift to Sanders, the Vermont senator still lags in support from superdelegates. Clinton has won over 469 superdelegates so far, while Sanders only has 31.

Clinton, who did not make a speech or hold an event following the Wisconsin primary, tweeted her congratulations to Sanders.



Looking ahead to future contests, Sanders urged supporters for large turnout in Wyoming, which holds its caucus on Saturday.

"We have a path toward victory, a path toward the White House and Wyoming can give us a huge boost forward if we win here on Saturday," Sanders said.

He also pointed to New York, which holds its delegate-rich primary on April 19. While Sanders grew up in Brooklyn, polls show him trailing Clinton by double digits in the Empire State, where she served as senator.

But that hasn't deterred Sanders from feeling optimistic about his chances of claiming victories in New York and states in the West.

"I believe we have an excellent chance to win New York and delegates," Sanders said. "Then we’re going to head out to the West Coast, and I think we have an excellent chance in Oregon and California
