Acting isn't Rosario's only passion. In 2004, she co-founded a nonpartisan organization called Voto Latino. She says her goal was to mobilize Latino voters by going door-to-door in states like Colorado and registering new voters.
"I felt really strongly about telling people, especially minority people, saying your voice matters. It doesn't even matter if you vote for the person who doesn't win. It's just important that you use it," she says. "I can't tell people that their voice matters only if you check this box. So I had to just go out there and just push really hard."
In all, Rosario says Voto Latino registered more than 30,000 new voters in just four years. "It was so amazing to be a part of this election," she says.
