In September, Pew Research Center released polling data showing that most Americans knew few people who supported a different presidential candidate than they did. About 4 in 10 supporters of both Trump and Biden indicated that they had no friends planning on voting for the other candidate.
That idea probably holds true not only for friendships but for communities. In 2016, we looked at precinct-level results to determine that a large percentage of voters in a number of states lived in neighborhoods where the margin between Trump and Hillary Clinton was at least 50 percent. The states where the most people lived in such neighborhoods were heavily ones that supported Trump.
