These may not be the best numbers, but they are below average errors, i.e., as I suggested previously, the average error in the last week's national polls for all presidential elections between 1952 and 2020 is 2.5 points, and it is larger still in the states.

Pollsters always said it would be close, and that either candidate could win every swing state. That’s exactly what happened.

Polls are almost always at least a bit off. Some of that is due to imperfect assumptions about what the likely voter electorate will look like. Some of that is due to statistical error. The 2024 presidential election was no different.
