Comment: "I think the inaccuracy of polling results before the 2016 election has already become notorious, yet it is still worthy of discussion. To summarize, election polling faces a crisis due to the growth of cell phones and a decline in survey participation, making it more expensive to conduct high-quality research. With cell phones now used by 43% of the population, manual dialing for cellphone interviews is time-consuming and costly, resulting in compromises in sampling and interviewing. The rapidly declining response rate, down to 8%, is also a concern, as it impacts representativeness and increases costs for survey organizations. The shift to online polling poses challenges, including coverage error and difficulty drawing a representative sample of Internet users. As a result, election polling is becoming less accurate, and there is no immediate solution to address these challenges, leading to experimentation and uncertainty in the field. This interview from the Pew Research goes deeper into the errors of preelection polling in 2016-2020, yet does not provide the answer to the question f how the sampling can be made more represantative
