Nate asks, “So how much did turnout contribute to Mr. Trump’s victory? As the party registration numbers and turnout figures by race imply, just a bit. But Mr. Trump won the election by just a bit — by only 0.7 percentage points in Pennsylvania, for example.”
That seems reasonable.
Let’s take a closer look at the precinct results in Florida.
Trump crushed Clinton across Florida’s precincts that had high voter turnout, as the figure below reveals (with the size of the precincts weighted by the total votes cast). Trump won a greater share of the total votes cast in the smattering of low turnout precincts, but more impressively, in precincts with turnout (of registered voters) that exceeded 75%. For example, he won more than 60% of the total votes cast (which includes write-ins and 3rd party votes) in precincts with greater than 90% turnout.
Trump also crushed Clinton in precincts that had high rates of Whites voting on Election Day. The figure below reveals that Trump won bigly in precincts in which Whites comprised more than 65% of those who waited until Election day to turn out (precinct size is weighted by Election Day Turnout).
So, it appears that that Trump did well in Florida not only in precincts with high voter turnout, but also in those where White voters turned out on Election Day.

Reprecincting and Voting Behavior

Despite the expansion of convenience voting across the American states, millions of voters continue to cast ballots at their local precincts on Election Day. We argue that those registered voters who are reassigned to a different Election Day polling place prior to an election are less likely to turn out to vote than those assigned to vote at the same precinct location, as a new precinct location incurs both search and transportation costs on reassigned voters. Utilizing voter file data and precinct shape files from Manatee County, Florida, from before and after the 2014 General Election, we demonstrate that the redrawing of precinct boundaries and the designation of Election Day polling places is not a purely technical matter for local election administrators, but may affect voter turnout of some registered voters more than others. Controlling for a host of demographic, partisan, vote history, and geospatial factors, we find significantly lower turnout among registered voters who were reassigned to a new Election Day precinct compared to those who were not, an effect not equally offset by those voters turning to other available modes of voting (either early in-person or absentee). All else equal, we find that registered Hispanic voters were significantly more likely to abstain from voting as a result of being reassigned than any other racial group.
