The Democratic nominee is favored by 65 percent of all Hispanics compared with 21 percent for the Republican nominee, according to data from Gallup's annual Minority Rights and Relations poll, conducted from June 7 to July 1.
Among those born in another country, the margin is 87 percent vs. 13 percent. But among U.S.-born Hispanics, it's tighter at 43-29 percent.
Actually, U.S.-born Hispanics' views of the candidates are similar to all national adults. Among all adults, it's 44 percent for Clinton and 34 percent for Trump.
The percentage of U.S.-born Hispanics registered to vote (87 percent) is less than non-Hispanics (95 percent).
Just 28 percent of Hispanics born outside the United States say they are registered to vote.
"This lower voter registration rate could be related partly to citizenship issues, as some foreign-born Hispanics may not be legal U.S. citizens, and therefore are ineligible to vote," Gallup said.
Overall, 58 percent of all Hispanics said they are registered to vote compared with 51 percent in 2013.
The Gallup survey consisted of a random phone sample of 3,270 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia with a margin of error of 3 percentage points. For results based on the total sample of 1,320 non-Hispanic whites, the margin of error is 4 percentage points. For results based on a sample of 906 Hispanics, the margin of sampling error is 6 percentage points, including interviews conducted in Spanish for those who are primarily Spanish-speaking.
All respondents previously were interviewed in the Gallup Daily tracking survey.
