“The demographic breakdown of the respondents was 72-14-8-6% white/black/Hispanic/other, while the party registration of respondents was 42-39% Democratic/Republican (18% Independents).”
The demographic breakdown seems reasonable.
The Florida Hispanic vote is disproportionately Cuban Americans, who tend strongly Republican, so that may not be so shocking that Florida Hispanics favor Trump, when this President and his former Secretary of State have labored tirelessly to prop up the Castro brothers.
