An Outlier Poll on Trump vs. Biden That Still Informs – The New York Times

Theres usually a simple rule of thumb for thinking about outlying poll results: Toss it in the average, and dont think too hard about it. After all, outlying poll results are inevitable, simply by chance. When they occur, it shouldnt be any surprise.

But sometimes, that guidance gets a little hard to follow. The most recent ABC/Washington Post poll is proving to be one of those cases.

In a startling finding, the poll found Donald J. Trump and Ron DeSantis each leading President Biden by seven percentage points, with Mr. Biden trailing among young people and struggling badly among nonwhite voters. After a few days of relentless media conversation, even Ive been forced to abandon the usual rule of thumb.

Make no mistake: This survey is an outlier. The Post article reporting the result acknowledged as much. But of all the cases over the last few years when an outlier has dominated the political discourse, this may be one of the more useful ones. For one, it may not be quite as much as an outlier as you might assume. Even if it is, it may nonetheless help readers internalize something that might have been hard to believe without such a stark survey result: Mr. Trump is quite competitive at the outset of the race.

To the extent the usual rule of thumb would mean dismissing the poll result and returning to an assumption that Mr. Trump cant win, the usual guidance might be counterproductive.

Before I go on, I should acknowledge that I do have a few gripes with this survey. It reported the results among all adults, not registered or likely voters. The question about the presidential matchup explicitly offered respondents the option to say theyre still undecided, which could tend to disadvantage the candidate with less enthusiastic support. For good measure, the matchup was buried 16th in the questionnaire, following other questions about the debt ceiling, abortion, the presidential primary, the allegations against Mr. Trump and so on.

But my various gripes probably dont explain Mr. Trumps strength. The poll actually did report a result among registered voters and still found Mr. Trump and Mr. DeSantis ahead by six. And just a few months ago, an entirely different ABC/Post survey asked about the presidential matchup among registered voters in the typical way, without offering undecided as an option. What did they find? Mr. Trump still led by three points among registered voters. Similarly, they found him leading by two last September.

Interestingly, the January and September surveys showed all of the same peculiar results by subgroup Mr. Trumps lead among young voters (18 to 39), and the staggering Democratic weakness among nonwhite voters. And while this was not included in the most recent poll, Mr. Trump led among voters making less than $50,000 per year, historically a Democratic voting group. No other high-quality survey has consistently shown Mr. Biden performing so poorly, especially among young voters.

All of this means that the ABC/Post poll isnt quite like the usual outlier. This consistent pattern requires more than just statistical noise and random sampling. Something else is at play, whether thats something about the ABC/Post methodology, the underlying bias in telephone response patterns nowadays, or some combination of the above. It should be noted that the ABC/Post poll is nearly the last of the traditional, live-interview, random-digit-dialing telephone surveys that dominated public polling for much of the last half-century. So its easy to understand why it could produce different results, even if its not obvious why it produces them.

But if no other survey has matched the ABC/Post poll, it would probably be wrong to say that its entirely alone in showing a weak Biden. Yes, its alone in showing Mr. Trump ahead by seven (counting leaners). But even the last Times/Siena poll, in October, showed Mr. Trump ahead by one point among registered voters. So far this year, the average of all polls has shown an essentially tied race.

And virtually all of the polling shows an admittedly more muted version of the same basic demographic story, especially among nonwhite voters. Even excluding ABC/Post polling altogether (in clear violation of the toss it in the average rule), Mr. Biden still has a mere 49-37 lead over Mr. Trump among Hispanic voters and just a 70-18 lead among Black voters. In each case, Mr. Biden is far behind usual Democratic benchmarks, and it comes on the heels of a midterm election featuring unusually low Black turnout.

If the lesson from the ABC/Post poll is that Mr. Biden is vulnerable and weak among usually reliable Democratic constituencies, then perhaps the takeaway from an outlying poll isnt necessarily a misleading one.
