How did Trump do among Cuban-born voters in Florida?

The following analysis comes from an extensive database my team and I have put together. It combines individual-level information of Florida voters (including where they were born) with precinct-level results.

The following graph plots precinct-level results. The size of the precincts are scaled to the total votes cast in a precinct in the 2016 General Election.  The Y-Axis is vote two-party share for Trump and Clinton. The X-Axis is the proportion of Hispanic voters in the precinct who are Cuban-born. Each precinct has at least 100 Cuban-born voters and at least 50% of voters were Hispanic.

As the LOWESS curves reveal, as the share of voters who are Cuban-born Hispanics increases, Trump’s share of the two-party vote steadily increases, intersecting with Clinton’s share of the vote around 42 percent of Cuban-born Hispanics, but then peaking at roughly 55 percent of the vote when the proportion of Cuban-born Hispanic voters reaches roughly 50 percent.

Although Trump won more than 60 percent of the two-party vote in a handful of these majority Hispanic precincts with a prevalence of Cuban-born voters, in Miami-Dade Precinct 335 (Hialeah), where 60 percent of the Hispanics who cast ballots were Cuban-born, Trump won less than 45 percent of the two-party vote.
