Reading Notes

• This report includes only registered voters.
• References to Republicans and Democrats throughout include respondents who initially identify as either a Republican or Democrat, as well as those who do not initially identify as a Republican or Democrat but who say they “are closer to” one of those parties (i.e., “leaners”) in a follow-up question. The category “Independents” does not include any of these “leaners.”
• For tabulation purposes, percentage points are rounded to the nearest whole number. As a result, percentages in a given chart may total slightly higher or lower than 100%. Summed response categories (e.g., “strongly support” + “somewhat support”) are rounded after sums are calculated. For example, in some cases, the sum of 25% + 25% might be reported as 51% (e.g., 25.3% + 25.3% = 50.6%, which, after rounding, is 51%).
• All questions included in this report, other than the question reported in section 2.1, were also asked in our March 2021 survey. All changes in opinion (i.e., differences in percentages) since March that are noted in the report text are outside the survey’s margin of error. Any changes in percentages from March to September that are not noted in the report text are within the survey’s margin of error.

  • Democrats (total) including leaners: 48%
    • Liberal Democrats: 26%
    • Moderate/Conservative Democrats: 22%
      • (Moderate Democrats: 18%; Conservative Democrats: 3%)
  • Independents excluding leaners: 10%
  • Republicans (total) including leaners: 37%
    • Liberal/Moderate Republicans: 14%
      • (Liberal Republicans: 1%; Moderate Republicans: 13%)
    • Conservative Republicans: 23%
