LOS ANGELES — Hillary Clinton is continuing to court millennial voters, with help from YouTube stars.

On Thursday, digital content studio Portal A — in partnership with the Hillary for America presidential campaign — launched an innovative, YouTube-focused video series designed to target millennial voters in key swing states: Florida, Pennsylvania and Ohio.

Todrick Hall, Glozell Green and Sam Tsui were tapped to kick off the ad campaign, called "One Vote At a Time."

The videos, which use the hashtag #strongertogether, feature the creators doing over-the-top surprises for three fans who are undecided voters.

Hall said he got involved after being approached and wanted to inspire others to vote.

"I've heard that this is the first year that the millennial vote could have the power to change the country, it just shows how much the world has evolved," Hall told Mashablein an email interview. "We aren't looking at two options in this presidential election, we are looking at one person who is an option to be the next president of the United States. We have the power to help young voters understand why this election is important and to encourage and inspire them to get out and vote for Hillary Clinton"

For his video, Hall went to Philadelphia to meet a fan. There he performs a flash mob dance to an original song featuring lyrics including, “It’s up to you."

In Glozell's video (below) she jumps into a swimming pool full of cereal to convince one of her fans to vote.

Tsui's video is coming soon.

The videos come several months after Clinton held a Digital Content Creators Town Hall in Hollywood.

There, participants — including Swoozie, Jennxpenn and Cassey Ho — asked Clinton questions on a variety of topics including immigration, education and climate change. 

Clinton's team has long been working to boost the presidential candidate's profile among millennials.

In the last year, the former secretary of state has already joked around with her on-screen doppleganger Kate McKinnon in a Saturday Night Liveepisode in October and appeared in an episode of Comedy Central's Broad City. She has appeared on The Conversation WithAmanda de Cadenet, where she chatted with GloZell, Chriselle Lim and Maya Washington.

"Our focus on millennials is integrated into every aspect of this campaign," Jason Rosenbaum, the campaign's director of digital advertising, told Mashablein an email. "These three YouTube influencers share Hillary Clinton's vision for a fairer, more equal and just world."

YouTube has also played an important role in this election.

People have watched more than 110 million hours of candidate and issues-related content leading up to November, YouTube said. Since the July conventions, more than 200,000 election videos have been uploaded to the platform.

According to a recent study commissioned by YouTube, one in three voters seek content by YouTube creators — and of those who do seek out content, almost half do so because they admire those creators.

"YouTube influencers have enormous reach and dedicated followings. Todrick Hall, Glozell Green and Sam Tsui have a combined 10 million subscribers on YouTube alone," Rosenbaum added.

The videos are now on the creators channels, as well as the Hillary for America channel.
