in Georgia, he has increased his share of the vote by 0.9 percent since the debate, though the Republican Party is still ahead by 3.5 percent.
In Michigan, he has increased his vote share by 0.8 percent making him ahead of Trump by 0.4 percent, and in North Carolina he has also increased his vote share by 0.8 percent, though the Republicans are still ahead by 4 percent.
It feels like the difference is within the margin of error, but I have no clue since they didn’t cite the new poll or the old poll they are comparing it to.
Old conservatives do. All these polls have samples that are biased against young people and mobile phones. Error bounds have increased as smart phones increased their adoption.
I bet these polls are within a couple points of the reality, as they pretty much always have been (even in the era of cell phones). They specifically weight the results based on the expected non-response of various groups. They account for the most obvious objection that anybody could raise about a modern poll (this one).
You can’t use weighting to correct a fundamentally biased sample. Don’t you remember 2016 when pollsters predicted Hillary would win? Trump voters were intentionally not giving their true opinion (or not answering the questions).
It’s the same now, with Biden voters. Trump voters were embarrassed in 2016 but Biden voters are embarrassed now. So they don’t show up in polls.
The polls in 2016 were largely on target. Clinton won the popular vote by roughly the predicted margin and the few key swing states that lost her the race had results that were largely within the margin of error. Lots of people took 2016 as an indication that polling is no longer good. That’s the wrong lesson to learn from 2016; it just doesn’t match the facts.

I just can’t believe in any poll that uses landline telephones or any telephones really. Because, who answers an unknown call?

Exactly.
