The ads focus on her work on health care reform and college affordability, as well as immigration reform and "keeping families together," a phrase that references halting deportations.

Opening with video of Republican presidential candidates Donald Trump and Ted Cruz, the narrator says in a translation of the 30-second television ad, "It’s when things get tough that you see the friends by your side. There is no other candidate who has fought as hard for our families as Hillary Clinton."

The radio ad expands on those points, as it is one-minute long, and includes a campaign organizer giving supporters instructions to caucus.

The advertising push is targeted directly at Nevada's Hispanic population, which makes up a notable piece of the Democratic electorate in the state.

Clinton polls well ahead of Sanders in both South Carolina and Nevada, the two early voting states with more diverse electorates than in Iowa and New Hampshire, where Sanders is performing well. That has prompted many Democrats to believe that Clinton has a minority-voter firewall as the primary race goes on, protecting her from any momentum Sanders might earn in the first two contests.

Sanders and Clinton have incorporated calls for immigration reform as key pieces of their platform but the candidates have sparred over immigration in the past. Clinton has chided Sanders for voting against a 2007 immigration reform bill while she received flack for calling on child migrants to be sent back to their home countries.
