Does exposure to a mass migration event cause citizens to vote against incumbents? I offer an answer to this question by studying one of the largest acute periods of migration in the US, the case of the 1980 Mariel Boatlift during which roughly 125,000 Cubans fled to South Florida. I estimate the change in support for Republican presidential candidates in Miami using the synthetic control method and fixed effects regressions with a panel of county-level and archival precinct-level election results. I find that, while Miami voters dramatically increased their support of the Republican candidate in 1980, this shift was not a local consequence of the Boatlift. Instead, the evidence suggests that Cuban support for Reagan was not a local Miami response to the Boatlift—it happened in Cuban communities throughout the US—but it was most noticeable in Miami because Miami had the largest Cuban population in the US even before the Boatlift. I also present evidence that this change in Cuban voting may have been specific to Reagan and not a broader shift against incumbents or toward Republicans. These findings suggest that, in this case, direct exposure to migration did not lead citizens to dramatically change their voting behavior.
