Reading Notes

• References to Republicans, Democrats, and Independents include only registered voters. References to Republicans and Democrats include registered voters 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.”
• In data tables, bases specified are unweighted, but percentages are weighted.
• 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 (e.g., 25.3% + 25.3% = 50.6%, which, after rounding, would be reported as 25% + 25% = 51%).
• 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: 9%
  • Republicans (total) including leaners: 42%
    • Liberal/Moderate Republicans: 15%
      • (Liberal Republicans: 6%; Moderate Republicans: 10%)
    • Conservative Republicans: 27%
  • No party/Not interested in politics/No response: 2%
