A new poll of registered Hispanic voters shows former San Antonio Mayor Julián Castro among the top five 2020 Democratic presidential contenders.

The poll, conducted in English and Spanish by polling firm Latino Decisions and the National Association of Latino Elected and Appointed Officials (NALEO), otherwise shows results similar to polls among all voters.

Castro is the only Hispanic currently running for president.

Latino voters will play a key role in the early 2020 Democratic primaries, as the early March Super Tuesday contests will feature California and Texas, the two states with the largest Latino populations.

Castro, a former Housing and Urban Development secretary under President Obama, has been struggling to stay in the top 10 of an ample and growing Democratic field.

The Castro campaign did not immediately return a request for comment.

In the Latino Decisions/NALEO poll, Buttigieg placed ninth in favorability ratings, with 31 percent of respondents viewing him positively.

Hispanic registered voters have historically been more or less as likely to vote as registered voters from other demographic groups, but the Hispanic community lags in voter registration.

A wide majority of poll respondents, 84 percent, said they would probably or almost certainly vote in 2020. Only 6 percent said they probably or definitely would not vote.
