I get texts ALL. THE. TIME. for surveys like this. It's just another spam text. I actually went through all the hassle of filling the goddamn thing out one time because they were asking about a local office and I really cared about the candidate I wanted to win.
It was like 30 pages of questions asking the same three questions from every direction possible, and when I went to submit it there was an error and it told me I would not be able to submit or retake the survey.
The New York Times/Siena College poll of 1,329 registered voters nationwide, including an oversample of 818 registered Republican voters, was conducted in English and Spanish on cellular and landline telephones from July 23-27, 2023. The margin of sampling error is plus or minus 3.67 percentage points for all registered voters and plus or minus 3.96 percentage points for the likely Republican primary electorate
Landline and cellular plus an oversample of republicans? Maybe someone better at statistics can say why that was needed
Do they still really do landline polls? No one I know has a landline anymore. My neighbor tried to get one and the phone company told her it wasn't possible.
It depends on your area. I live in a more rural area currently, and landlines are decently common. They're more reliable than a cell phone depending on where you're at. Some people even have them run out to their barns/buildings, just in case something happens.
