I can think of four strikes against it off the top of my head.
1. It’s a poll of registered, not likely, voters. Virtually every other pollster has been focused on likely voters for weeks.
2. It’s an outlier. No other poll lately shows a lead for Biden this big, including other polls released yesterday.
3. It’s outdated. Even if it’s on the mark, this poll was conducted before Trump announced he had COVID. In 2020, when 17 blockbuster news stories happen every day, no poll is accurate for more than like 45 minutes.
4. This same pollster had Hillary Clinton up by — ta da — 14 points right around this time in 2016. How’d that race turn out?
