The US presidential election remains on a knife-edge 45 days before voters go to the polls, despite Kamala Harris enjoying one of her most encouraging spells of opinion polling since becoming the Democrats’ nominee nearly two months ago.
During yet another momentous week that began with a suspected second assassination attempt against Donald Trump, the latest Guardian 10-day polling averages survey shows Harris increasing her lead to 2.6 points, 48.5% to 45.9%.
While still within error margins, that is an improvement of the 0.9% edge Harris held last week and a significant shift from the statistical dead heat of a fortnight ago before the candidates held their only scheduled televised debate in Philadelphia on 10 September.
But again, how can they accurately get that in terms of opinion when so few people under 30 are willing to answer their phones? It doesn’t matter what your demographics are when you’re still restricted to the small number of people under 30 that are willing to answer their phones, making them outliers to begin with.
Their lists are millions of names long. It takes them a lot longer than it did 30 years ago, but they slog away at it until they get enough.
I would suggest that the fact that the polls are all over the map supports my point.
It’s faster. They use more methods than just calling, but the calls can be automated and the data entry digitized. (I know there are restrictions on robodialing, but I’m sure surveys have an exemption or approval process.)
Nanos in Canada still does it the old way.
