A New York Times analysis of precinct-level election results in 11 big cities reveals that Kamala Harris received 15 percent fewer votes than Joe Biden in some urban areas, contributing to the Democrats' loss of ground since 2020. In Atlanta, Harris's gains in precincts with white voters were offset by losses elsewhere, allowing Trump to win Georgia. Chicago saw a decline in Democratic votes in strongholds, with Harris losing ground in nearly every precinct. In Wayne County, Detroit, Harris struggled to capture the support of Arab-American voters, while in Houston, she underperformed Biden's 2020 vote totals, particularly in Latino neighborhoods and low-income areas. Miami-Dade County flipped to Trump due to his increased support among Latino voters from various groups.
