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%).
• Weighted percentages among registered voters of each of the groups discussed in this report:
  • Democrats (total) including leaners: 48%
    • Liberal Democrats: 27%
    • Moderate/Conservative Democrats: 21%
      • (Moderate Democrats: 19%; Conservative Democrats: 3%)
  • Republicans (total) including leaners: 39%
    • Liberal/Moderate Republicans: 12%
      • (Liberal Republicans: 1%; Moderate Republicans: 12%)

  • Independents excluding leaners: 8% (included the in results reported for “All Registered Voters” only)
