Morning Consult | Bloomberg News Survey: Biden’s and Trump’s Ballot Performance as of March 2024

Methodology

The Bloomberg News/Morning Consult poll surveyed 4,932 registered voters in seven swing states: 796 registered voters in Arizona, 788 in Georgia, 698 in Michigan, 447 in Nevada, 699 in North Carolina, 807 in Pennsylvania and 697 in Wisconsin. The surveys were conducted online beginning March 8, and concluded March 14 in Arizona and Wisconsin, March 15 in Nevada, and March 12 in the remaining states. The aggregated data across the seven swing states were weighted to approximate a target sample of swing-state registered voters based on gender, age, race/ethnicity, marital status, home ownership, 2020 presidential vote and state. State-level data were weighted to approximate a target sample of registered voters in the respective state based on gender, age, race/ethnicity, marital status, home ownership, and 2020 presidential vote. The margin of error is plus or minus 1 percentage point across the seven states; 3 percentage points in Arizona, Georgia and Pennsylvania; 4 percentage points in Michigan, North Carolina, and Wisconsin, and 5 percentage points in Nevada.
