Math is math. In order to calculate the margin of error you need to know the sample size. The number of months involved is not a part of the calculation.
Then it’s not margin of error, the predictive accuracy - whatever the term is - is far worse 6mo out from an election (5 now i guess) than the ones that are days or a week or so out. That’s the point. Polls now are useful but not for saying who will win in November. You may as well forget the top line numbers as soon as you see them unless you’re comparing them over time and/or looking at cross tabs for broad demographic trends, which is also limited but useful in some ways.
I mean Larry sabato just cited this stat days ago but I’m sure you’ll say he knows nothing.
You can average the top performing polls to get this.

Fair enough… if we both agree that “margin of error” has nothing to do with number of months; I have no argument.
