In the past few weeks, Pollster has begun reporting multiple results for a single poll. Some polling organizations have been reporting separate results for Democratic, Republican, and independent respondents, as well as the aggregated data for all respondents. They have also begun providing detailed information on the question(s) asked to determine voting intention. Pollster reports separate results for each question wording.
Since all my analyses use just one entry per poll, I have begun removing this extra data before analysis. Unless specifically stated, I am using only the first “question iteration” for each poll (coded “1” at Pollster) and only data for the entire population. Using the first iteration helps insure consistency across all the polls from a single organization.
