New York Times: “Data for Progress researchers have gotten used to being told to take a hike — and worse — by Trump supporters they try to poll, and the report detailed their difficulties in reaching that group. But perhaps most significantly, it also found that they were having trouble reaching a representative sample of Democrats, as well as Republicans — partly because liberals with strong political views were almost too willing to be polled.”

Geoffrey Skelley: “In a February poll taken on behalf of Democracy for All 2021 Action, which backs efforts to admit D.C. as a state, Data for Progress found that 54 percent of likely voters backed statehood while just 35 percent opposed it. However, DFP told respondents that statehood would give congressional voting representation to more than 714,000 Washingtonians, ‘just like Americans in every other state,’ so this question framing likely primed respondents to be more favorable toward statehood.”

“Bottom line: How you ask a poll question matters.”

Nate Silver: The death of polling is greatly exaggerated.

Laura Bronner: “How many Americans support legalizing marijuana? Sixty-eight percent, per Gallup. And according to Morning Consult/Politico, 60 percent think the minimum wage should be increased to $15 an hour by 2025. But how much stock should we really be putting into polls like this, especially given the polling error we saw in the 2016 and 2020 elections?

“Turns out, there are a number of reasons why we shouldn’t be too worried. according to a new Pew Research Center study, which analyzed nearly a year’s worth of its polls asking Americans how they felt about a variety of issues.”

Emily Ekins: “But why are some Republican voters more reluctant to take surveys? As the director of polling at the Cato Institute, I, as well as other pollsters, am studying this and currently have two working theories for why this is happening.”

“First, Republicans are becoming more distrustful of institutions and society, and that may be extending to how they feel about pollsters. Second, suburban Republican college graduates are more likely to fear professional sanction for their views and are therefore self-censoring more, including in surveys.”

Rep. Sean Patrick Maloney (D-NY), the chairman of the House Democratic campaign arm, said he’s doing a deep dive into the party’s election failures in 2020, including a look at “why the polling sucked,” The Hill reports.

“Maloney said the Democratic Congressional Campaign Committee has commissioned a report examining why the party lost more than a dozen House seats over the course of an election in which they won the White House and a majority in the Senate.”

Geoffrey Skelley: “So what happened? Were the polls just terribly off in 2020? Not dramatically, no. Yes, polls once again underestimated Donald Trump’s performance, but the magnitude of that error (about 4 percentage points) wasn’t all that different from past presidential contests, such as in 2012 when polls underestimated Barack Obama’s margin of victory by almost 4 points. And there have, of course, been much larger polling errors, too.”

“But one reason the polling in 2020 has received so much attention is that down-ballot polling, namely the generic ballot — which asks respondents whether they plan to vote for a Democrat or Republican in their local race for the U.S. House of Representatives — was also off by a similarly large margin in 2020. In fact… the House popular vote was 4.2 points more Republican-leaning than the polls anticipated, making it the largest generic ballot polling miss in a presidential or midterm cycle since 2006.”

Pew Research: “Looking across the 12 battleground states from the upper Midwest (where many polls missed the mark) to the Sun Belt and Southwest (where many were stronger), polls overestimated the Democratic advantage by an average of about 4 percentage points. When looking at national polls, the Democratic overstatement will end up being similar, about 4 points, depending on the final vote count. That means state polling errors are about the same as in 2016, while the national polling error is slightly larger, at least as of today.”

“The fact that the polling errors were not random, and that they almost uniformly involved underestimates of Republican rather than Democratic performance, points to a systematic cause or set of causes. At this early point in the post-election period, the theories about what went wrong fall roughly into four categories, each of which has different ramifications for the polling industry.”

Pollster David Shor explains to Vox why the public polling was off this year:

“So the basic story is that, particularly after Covid-19, Democrats got extremely excited, and had very high rates of engagement. They were donating at higher rates, etc., and this translated to them also taking surveys, because they were locked at home and didn’t have anything else to do. There’s some pretty clear evidence that that’s nearly all of it: it was partisan non-response. Democrats just started taking a bunch of surveys when they were called by pollsters, while Republicans did not.”
