Latino voters could swing six battleground states in 2020, a new poll showed, sparking concern for Joe Biden and Democrats.

The poll by Voter Participation Center/Voto Latino showed low enthusiasm among Latinos in states where the population could affect the outcome, particularly among young voters—a finding that Stephen Nuño, a Latino Decisions pollster who conducted the poll, said is concerning for the presumptive Democratic nominee.

The poll surveyed 1200 Latino voters in the six battleground states of Arizona, Florida, Nevada, North Carolina, Pennsylvania, and Texas. Page Gardner, founder of the Voter Participation Center and the Center for Voter Information told Newsweek that taking the pulse of Latinos in those states is important because the burgeoning Latino populations could affect the election and they are the key battleground states not just in the presidential race, but have down-ballot implications. The poll is the first robust sample of Latinos in North Carolina and Pennsylvania this cycle.
