What I don't understand is why so much stock is put into the latest poll, as if it supersedes all previous information, and especially when election forecasters, such as Nate Silver, do such a good job of integrating the poll with all that other information. The reporting on the Selzer poll borders on fraud. For example, the lead sentence in the Des Moines Register's
article reporting the result was "Kamala Harris now leads Donald Trump in Iowa — a startling reversal for Democrats and Republicans who have all but written off the state’s presidential contest as a certain Trump victory."
That is just ********.
Arguably worse, if accurate, the article quotes Selzer herself: “'It’s hard for anybody to say they saw this coming,' said pollster J. Ann Selzer, president of Selzer & Co. 'She has clearly leaped into a leading position.'”
"Clearly" in a leading position? Does America's most esteemed pollster not know how to calculate a 95% confidence interval?
