Politics & Global Warming, December 2020

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 (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: 25%
      • Moderate/Conservative Democrats: 22%
        • (Moderate Democrats: 19%; Conservative Democrats: 3%)
    • Independents excluding leaners: 10%
    • Republicans (total) including leaners: 39%
      • Liberal/Moderate Republicans: 16%
        • (Liberal Republicans: 1%; Moderate Republicans: 14%)
      • Conservative Republicans: 23%
    • No party/Not interested in politics/No response: 4% (included in results reported for “All Registered Voters” only)
  • In the data tables, “0” denotes that the cell value is between 0.00 and 0.499…
  • In all tables, bases are unweighted and percentages are weighted.
