Lovato follows a string of youth-friendly celebrities to endorse the Democratic presidential candidate.

Over the past few months, Katy Perry, Lena Dunham, Abby Wambach and \"Scandal\" star Tony Goldwyn have all hit the trail on Clinton's behalf -- a move meant to woo youth voters, many of whom have rallied behind Sanders.

Whether the strategy will pay off at the polls is still to be seen.

Many of those in attendance tonight said they were still undecided about who they would caucus for in 11 days, but that Lovato’s endorsement of Clinton wouldn’t sway them either way.

\"I don’t think any celebrity would really influence my choice for president that much,” 23-year-old Grace Junkins told ABC News as she waited in line for the event.

Her friend, Jamie Pritzker, 20, who says she's between Sanders and Clinton, also dismissed Lovato as having any impact on her vote, but did admit the singer’s appearance was a factor in why she attended the event.

Other students — like Madisyn Martin, a 19-year-old Republican, who says she’s leaning towards Donald Trump — were clearly there with one intention only.

“I’m here for Demi,” Martin said. “That’s about it.”
