That was an interesting clip. The stats guy confirmed that the Dobbs decision has materially affected election outcomes since that date, partially from newly registered voters that are not easy to capture in polling. |
They looked at 13 states including Michigan and North Carolina. |
Pollsters will oversample if they want to do a deep dive into a particular subgroup's views. But oversampling is expensive because you need to keep calling more and more people until you have your oversample numbers. Instead, what they will do is adjust the weighting of certain groups. For example, lets say a Congressional district's voter turnout is traditionally 30% Latino/Hispanic. Well, you've talked with 1000 survey respondents but you only got 150 responses from Latinos/Hispanics (15% of sample). You could keep calling and get more Latinos, but that is expensive. Instead, what pollsters will do is take the 150 responses from Latinos and over-weight them to 30% of the overall "Total" results. Basically you're doubling the power of the 150 Latinos you spoke with...but what if there's something different from those 150 Latinos relative to the rest of the Latino population? Maybe more likely to be unemployed? Older? Etc. Pollsters have to do this re-weighting with multiple demographic groups in any given poll. A typical one is the 18-29 age bucket - pollsters have an extremely difficult time reaching this group. So the few interviews they get with Gen Z will be re-weighted and scaled up when calculating the overall results sometimes using just a few dozen interviews in a 1000 person poll. This age group also has large swings in voter turnout every four years, so its difficult to model what percentage will compose come Election Day. In short, polling is broken for lots of reasons - the weird self-selection of people who will talk to pollsters, difficulties in modeling turnout among a diversifying electorate, etc. |
Right, just as folks relied on NYT in '16 and they were so shocked when results came out. What does Prof Lichtman predict for '24 POTUS? |
Didn't the OP say if you have more than a few lines, discuss on another thread?? |
He said that while he will put out an official prediction after Labor Day, for now he thinks "a lot would have to go wrong for the Democratic Party to lose." Take that for what it is. https://www.miamiherald.com/news/local/news-columns-blogs/andres-oppenheimer/article291223915.html |
I think this post is about how polling is conducted, and therefore relevant. Once someone starts going off on tangents unrelated to polling, that should be reported to keep the thread from deteriorating. I don't think OP literally meant don't write more than a few sentences, but rather that larger paragraphs are indicative of non-polling related discussions. |
