The study says they used online polling but didn’t elaborate further so who’s to say what biases there may or may not be. But generally ipsos does a pretty good job with their polling.

I do agree that most of these polls tend to end up being nothing burgers, but there has been a recent trend of younger males gravitating towords the right of the political spectrum. I mainly commented to point out that a sample size of 1000 is generally recognized to be large enough for accuracy.
