Phoeenix (AP) — As ranchera music filled the Phoenix recording studio at Radio Campesina, a station personality spoke in Spanish into the microphone.

“Friends of Campesina, in these elections, truth and unity are more important than ever,” said morning show host Tony Arias. “Don’t let yourself be trapped by disinformation.”

The audio was recorded as a promo for Radio Campesina’s new campaign aiming to empower Latino voters ahead of the 2024 elections. That effort includes discussing election-related misinformation narratives and fact-checking conspiracy theories on air.

“We are at the front lines of fighting misinformation in our communities,” said María Barquín, program director of Chavez Radio Group, the nonprofit that runs Radio Campesina, a network of Spanish-language stations in Arizona, California and Nevada. “There’s a lot at stake in 2024 for our communities. And so we need to amp up these efforts now more than ever.”

Latinos have grown at the secondfastest rate, behind Asian Americans, of any major racial and ethnic group in the U.S. since the last presidential election, according to a Pew Research Center analysis, and are projected to account for 14.7%, or 36.2 million, of all eligible voters in November, a new high. They are a growing share of the electorate in several presidential and congressional battleground states, including Arizona, California and Nevada, and are being heavily courted by Republicans and Democrats.

Democratic President Joe Biden has credited Latino voters as a key reason he defeated Republican Donald Trump in 2020 and is urging them to help him do it again in November.

Given the high stakes of a presidential election year, experts expect a surge of misinformation, especially through audio and video, targeting Spanish-speaking voters.

“Latinos have immense voting power and can make a decisive difference in elections, yet they are an under-messaged, under-prioritized audience,” said Arturo Vargas, CEO of NALEO Educational Fund, a national nonprofit encouraging Latino civic participation. “Our vote has an impact. These bad actors know this, and one way to influence the Latino vote is to misinform.”

In addition to radio, much of the news and information Latinos consume is audio-based through podcasts or on social media platforms such as Facebook, WhatsApp and YouTube. Content moderation efforts in Spanish are limited on these platforms, which are seeing a rising number of right-wing influencers peddling election falsehoods and QAnon conspiracy theories.

The types of misinformation overlap with falsehoods readily found in other conservative media and many corners of the internet — conspiracy theories about mail voting, dead people casting ballots, rigged voting machines and threats at polling sites.
