Rick, Landlines, cell phones, internet and more. Here’s how Pew Research select those who they poll - How are people selected for your polls?
Most of our U.S. surveys are conducted on the American Trends Panel (ATP), the Center’s national survey panel of over 10,000 randomly selected U.S. adults. ATP participants are recruited offline using random sampling from the U.S. Postal Service’s residential address file. Respondents complete the surveys online using smartphones, tablets or desktop devices. We provide tablets and data plans to adults without home internet.
And - The Quinnipiac University Poll uses what has long been considered the gold standard methodology in polling: random digit dialing using live interviewers, calling both landlines and cell phones. This methodology has been the key to our accuracy over our many years of polling.
That’s but two examples, if your interested in the changes made - How Public Polling Has Changed in the 21st Century
https://www.pewresearch.org/methods/2023/04/19/how-public-polling-has-changed-in-the-21st-century/What I like to use is RCP and their polling average of all the recent polls when possible. Averaging eliminates the strength of an outlier poll. RCP averages has been accurate within the MOE of the polls for about every election. Pundits and opinion pieces tend to pick and choose the polls that backs up whatever they’re trying to say. RCP by averaging also eliminates the pick and choose pundits and opinion pieces. Although at times there isn’t any choice but to rely on a single poll depending on what one is looking for. RCP doesn’t cover voter enthusiasm, but YouGov does. So, I have no choice but to rely on YouGov. As for polling firm’s accuracy and reputation. You have this from 538.
