Introducing 538's new 2024 presidential polling averages for Kamala Harris versus Donald Trump.
As of Friday at 10 a.m. Eastern, our average of national polls says Harris has the support of 45.0 percent of voters, while Trump garners 43.5 percent.
That 1.5-percentage-point lead is within our average's uncertainty interval, which you can think of as a sort of margin of error for our polling averages.
It's a little weird that they say Harris is "tied" with trump, even though she's ahead by 1.5%. That seems like a big deal. Margin of error is important, but it's just factually true that Vice President Harris is up by an average of 1.5%.
I looked back at how 538 treated polls when trump was up by a similar amount:
In 538's national polling average, Trump now leads by 1.4 percentage points over Biden, while the two candidates were just about tied on June 27, the day of the debate.
So Harris up by 1.5% is actually "tied", but trump up on Biden by 1.4% is "leads" (and explicitly different from "tied"!). No mention of margin of error in that paragraph.
National polling averages are nice and all, but what's the situation in the critical swing states? Popular vote should be fairly meaningless unless either side is up but like 25 points.
Fairly promising, at least in relation to Biden v Trump numbers
AZ: mostly even
GA: mostly even
MI: mostly even, Harris with a lead depending on how much you trust Morning Consult's numbers
MN: Harris leads
NV: mostly even
WI: mostly even, slight lead for Harris
If I'm remembering right, most of those had Trump leading prior to Biden dropping out
Yeah I think youāre right about these states polling differently following Bidenās withdrawal. Pretty sure I remember trump being ahead in at least 4 of that set.
There's some value versus knowing nothing. But until October early voting actually begins, not worth obsessing over. To be fair, their forecast was still one of the better ones for that infamous election, dropping around 60-40 Clinton during election day (NYT was still 90-10). And I'm sure many things were learned from it, maybe even over-corrected, based on '20-22. I'll be following Nate's Silver Bulletin this year (he left 538 and took his algorithms).
