Iowa Pollster: I’m a ‘Big Believer of Keeping My Dirty Fingers off the Data’

EXCERPT:

SELZER: "We first saw the numbers on Tuesday morning, Monday night was the first night in the field. I walked into the office and overnight I'd seen the unweighted data and it had Harris leading. My assistant said, 'Did you see the data?' I said, 'I would like to see the weighted data.' So, the weighting is how we take care of thing that would make our poll unrepresentative. We align things with a known population and we extract from a larger group, the people who meet our definition of likely voters. That is people who have already voted, and people who say they will definitely vote. So, when former President Trump says we interviewed more Democrats, well, that is what came out of our data. We did nothing to make that happen. I‘m a big believer of keeping my fingers off — my dirty fingers off the data. So, we did it the way we did it. When he won in our final poll twice, in two election cycles, the very same method."
