Yeah I wouldn't put too much stock in this. The % of persuadable voters in this is massive for both candidates. This isn't the same thing as asking people whom they would actually vote for if forced to make a decision (including the decision to not vote at all). And that explains why it's so wildly out of sync with the general election polling that has been coming out the last couple of months. Most of that has either Biden or Trump winning by some amount that's squarely within the margin of error. The battleground state polling, in particular, is definitely moving in the right direction for Trump and the wrong direction for Biden. (Though that shifts a lot and will continue to)
