Abstract

AIM: This study investigates whether assault frequency increased on days and in cities where candidates Donald Trump and Hillary Clinton held campaign rallies prior to the 2016 US Presidential election.

METHOD: We calculated city-level counts of police-reported assaults for 31 rallies for Donald Trump and 38 rallies for Hillary Clinton. Negative binomial models estimated the assault incidence on rally days (Day 0) relative to that on 8 control days for the same city (Days -28, -21, -14, -7, +7, +14, +21, and +28).

RESULTS: Cities experienced an increase in assaults (Incidence Rate Ratio [IRR]=1.12, 95%CI: 1.03-1.22) on the days of Donald Trump's rallies, and no change in assaults on the days of Hillary Clinton's rallies (IRR=1.00, 95%CI: 0.94-1.06).

CONCLUSION: Assaults increased on days when cities hosted Donald Trump's rallies during the 2016 Presidential election campaign.
