Clinton’s 60 percent to 30 percent advantage over Trump with Florida Hispanics overall is fueled by outsized support from voters of Puerto Rican descent, who favor her 71 perccent to 19 percent, according to the survey of 800 likely Hispanic voters jointly conducted for Univision by Republican-leaning Tarrance Group and Democratic-leaning Bendixen & Amandi International.

Trump, meanwhile, has relatively weak backing from Cuban-Americans. They historically vote Republican but only support him over Clinton by 49 percent to 42 percent, the poll shows. And Hispanic voters of other national origins heavily prefer Clinton over Trump by 71 percent to 20 percent. The overall margin of error for the poll is 3.5 points.

“These Florida numbers are not only ominous for Donald Trump — they’re downright terrifying for Republicans nationwide,” said Fernand Amandi, Bendixen & Amandi’s pollster, who called Clinton’s 30-point margin “historic.”
