Nevada Rep. Jacky Rosen’s Senate campaign announced its first major digital buy Friday, launching ads in both English and Spanish aimed at Latino voters. The freshman Democrat is challenging Republican incumbent Dean Heller in a race that could be one of her party’s best pickup opportunities in the Senate.

The digital ads, shared first with Roll Call, focus on Rosen’s background and her support for so-called Dreamers, young immigrants brought to the country illegally as children. The ads include a 30-second video and a shorter 15-second version, in both languages.

They highlight the importance of Latino voters as part of Rosen’s coalition for November. According to her campaign, the effort is part of a “substantial six-figure investment” in digital ads, and will run on Hispanic-focused local websites such as El Tiempo and El Mundo, and websites like YouTube and Hulu Latino. The language of the ad will be based on a the user’s browser language settings.

The video begins by introducing Rosen as the first in her family to graduate from college and highlights her career as a software developer. The ad then shifts to her support for Dreamers.

“In Congress, she didn’t back down. She voted against Trump to protect Dreamers,” the narrator says. “Jacky understands that dreaming is not sleeping. It’s working, sacrificing, saving.”
