Matching respondents were selected from the YouGov panel, an opt-in Internet panel.

Some respondents were initially selected on September 7-14 from YouGov¹s panel, then recontacted on October 4-11 and again on October 31-November 3.  Others were selected for the first time on October 31-November 3.

Weighting: The sample was weighted using propensity scores based on age, gender, race, education, news interest, and non-placement on an ideology scale.
