What's the argument here, that the advent of the Harris ticket has repulsed the nation but enthused Wisconsin? The national picture is just the aggregate of local ones. Of course there are discrepancies, it's just that they don't often head out in diametrically opposed directions. It signifies that at least one of them is wrong.
The argument is simply that discrepancies between state polls and national polls are a normal part of American politics, and therefore should not be surprising. Indeed, discrepancies between any polls are a fairly normal occurence.
I’m honestly pretty confused how you don’t understand that point, and why such a discrepancy is necessarily “weird”.
Describing those two polls as being “in diametrically opposed directions” just doesn’t make sense either when they show a swing of just four percentage points for each candidate, especially when you consider typical margins of error in political polls, and the fact that other polls from that state, and other national polls, show different results.
But even when there is a discrepancy like that, both polls could still be right because they are polling different things. By definition a national aggregate of the polling from 50 states cannot align with every single poll result from each of those individual states, unless the poll results from each state are all exactly the same (which has never ever happened in a presidential race).
Additionally, there are myriad things that can affect polling within individual states that aren’t accounted for at the national level. Demographic changes, performances of state incumbents, regional economic and social drivers etc.
As long as she didn't end up being a Covid denier or something.
