Reading notes

  • This report is based only on 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 Republicans or Democrats but who say they “lean” toward one party or the other in a follow-up question. The category “Independents” does not include any of these “leaners.”
  • In all tables and charts, bases specified are unweighted, but percentages are weighted.
  • Weighted percentages among registered voters of each of the groups discussed in this report:
    • Democrats (total) including leaners: 47%
      • Liberal Democrats: 26%
      • Moderate/Conservative Democrats: 21%
        • (Moderate Democrats: 17%; Conservative Democrats: 4%)
      • Independents excluding leaners: 10%
      • Republicans (total) including leaners: 37%
        • Liberal/Moderate Republicans: 15%
          • (Liberal Republicans: 3%; Moderate Republicans: 12%)
        • Conservative Republicans: 22%
      • No party/Not interested in politics/Refused: 6% (included in results reported for “All Registered Voters” only)
  • In the appendix tables, note that: — = 0; * = >0 but <0.5.
  • For tabulation purposes, percentage points are rounded off 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 (e.g., 1.3% + 1.3% = 2.6%, which, after rounding = 3%).
