Iowa: Questioning the Polls

By Jim Ellis

Oct. 19, 2020 — Every political observer remembers that the cumulative polling community incorrectly predicted the Great Lakes states of Michigan, Pennsylvania, and Wisconsin in the 2016 Trump-Clinton presidential race, but further research finds additional significant misses in succeeding elections.

Political research reveals that two of those campaigns came in Iowa during the 2016 presidential race and the hotly contested governor’s race two years later. Today, we look at the Hawkeye State numbers with the goal of potentially ascertaining if there is a common polling pattern or consistent error factor.

In October, four polls have been released for the 2020 contest from a like number of different pollsters, two from left of center organizations while the other two are independent entities. The research organizations are Data for Progress, Civiqs for the Daily Kos Elections webpage, YouGov, and Quinnipiac University. Each has conducted one October Iowa survey.

In the presidential race, the polls yield former vice president Joe Biden an average lead of just over one percentage point. The cumulative ballot test mode then finds Des Moines real estate executive Theresa Greenfield (D) topping Sen. Joni Ernst (R) with a margin of four percentage points.

How do these numbers compare to recent polling vs. results electoral history, and is there an inherent Republican under-poll present?

In 2016, the Real Clear Politics polling average from Nov. 1-4 found then-candidate Donald Trump leading former Secretary of State Hillary Clinton by a mean average of three percentage points derived from three polls and three different polling firms. On Election Day, Nov. 4, 2016, Trump carried the state by a much larger 9.5-point margin.

Overall, 26 Iowa polls were released during the 2016 election cycle, with Trump recording a cumulative average lead of under half of one percentage point. According to the Real Clear Politics polling archives, 12 firms combined to reach the grand total, including Public Policy Polling (5 surveys), NBC News/Wall Street Journal/Marist College (5), Loras College (3), Quinnipiac University (3), Emerson College (2), and Selzer & Company for the Des Moines Register (2). The widest spread came from Loras College (Clinton plus-14) at the end of June. The Selzer & Company for the Des Moines Register poll produced the most accurate finding, Trump plus-7, at the very end of the election cycle (Nov. 1-4, 2016).

Georgia Polling Dichotomy

By Jim Ellis

Oct. 16, 2020 — An October polling plethora has been released in Georgia, which is becoming one of the most important 2020 election cycle states both in terms of the presidential and US Senate outcomes. As the only state featuring two US Senate races, Georgia has attracted more than its share of polling universe attention.

Quinnipiac University released new data yesterday that either is detecting a new trend or is an outlier. Their results give Democratic presidential nominee Joe Biden, and US Senate candidates Jon Ossoff and Raphael Warnock big leads in their respective races, something no other survey research firm is reporting.

The Quinnipiac poll (Oct. 8-12; 1,040 likely Georgia voters, live interview) finds Biden posting a 51-44 percent lead over President Trump, Ossoff claiming a similar 51-45 percent advantage over Sen. David Perdue (R), and Rev. Warnock outpacing both Rep. Doug Collins (R-Gainesville) and appointed Sen. Kelly Loeffler (R) by 19 and 21 percentage points (41-22-20 percent).

Six other pollsters, also surveying in October, largely see things much differently.

Polling within the same period as Quinnipiac are Survey USA, Data for Progress, and Morning Consult.

Survey USA chose exactly the same sampling period as Quinnipiac, Oct. 8-12. With a sample size of 877 likely Georgia voters also in live interviews, they see a dissimilar political landscape. While they find Biden leading in the presidential race, his margin is only two points, 48-46 percent.

The two pollsters’ Senate numbers are starkly different. S-USA finds Sen. Perdue leading Ossoff, 46-43 percent, a net nine-point variance when directly compared with Quinnipiac. The jungle primary special election race is even more disparate. While Quinnipiac projects one of the biggest leads for Warnock during the entire election cycle, S-USA finds only a four-point difference between he and Sen. Loeffler, 30-26 percent, a far cry from the Q-Poll’s 41-20 percent.

The two pollsters even see a different ballot test order. While the Q-Poll finds a Warnock-Collins-Loeffler split, Survey USA projects a virtual three-way battle among Warnock, Loeffler, and Collins. The latter poll posts Rep. Collins’ statewide support at 20 percent.

Sen. Lindsey Graham’s Challenge

By Jim Ellis

Is incumbent Sen. Lindsey Graham (R-SC) in re-election trouble?

Sept. 18, 2020 — Quinnipiac University surveyed the South Carolina political situation as part of their three-state polling series, which again produces some eyebrow-raising data. The results help identify why Sen. Lindsey Graham, a Republican senator from a Republican state, finds himself languishing in a competitive contest.

The poll (Sept. 10-14; 969 likely South Carolina voters, live interview conducted by the RDD firm for Quinnipiac) tested both the presidential and Senate campaigns. President Trump leads former vice president Joe Biden 51-45 percent in a ballot test that seems to be an under-count when looking at the survey’s supporting numbers. Sen. Graham, however, falls into a tie with opponent Jaime Harrison, at 48-48 percent, in a result that the underlying responses do seem to support.

President Trump’s six-point lead appears low because he tops Biden on virtually every personal and issue question. The Trump favorability index is 51:45 percent positive to negative, but the Biden ratio is much worse at 43:50 percent. The generic Republican-Democrat number falls 52-44 percent in favor of the GOP label.

Despite poor coronavirus management numbers for the president nationally, this South Carolina survey returns a 49:48 percent approval number on his handling of the issue. Furthermore, the respondents, in a 50-46 percent break, believe President Trump would do a better job handling coronavirus in the future than Biden. Not a particularly strong performance in this issue area, but better for the President than in almost any other place.

Trump also scores better in his handling of the economy (55-40 percent), the military (54-42 percent), and “keeping your family safe” (52-43 percent). Biden is favored, and only barely, 48-46 percent, on just one issue: racial equality.

Most importantly, the issue matrix sets up perfectly for Trump. The top two issues, according to these respondents, are the ones upon which the president is basing his campaign, law and order (23 percent) and bringing back the economy (22 percent). The Biden key issues rate rather poorly: coronavirus (12 percent), racial equality (12 percent), and healthcare (10 percent).

All of these underlying numbers suggest the Trump ballot test margin should be stronger than six points, which could be a signal that there is a “shy Trump voter factor” even in what is typically a safe Republican state. The “shy Trump voter” is the phrase now used to describe the individual who only secretly favors the president.

Senate Sleepers in Minnesota
and South Carolina

By Jim Ellis

Are incumbents Sen. Tina Smith (D-MN), left, and Sen. Lindsey Graham (R-SC) in re-election trouble?

Sept. 8, 2020 — At the beginning of the 2020 election cycle, it appeared that Sens. Tina Smith (D-MN) and Lindsey Graham (R-SC) were set for re-election. That no longer appears to be the case.

Polling is now consistently showing close races in the two states, and Sen. Smith’s recent comments about the police have seemingly moved her re-election campaign closer to the toss-up category according to a just-released Harper Polling survey.

Looking at the HP data (Aug. 30-Sept. 1; 50 likely Minnesota voters via live interview), Sen. Smith’s ballot test edge has dropped to just 43-41 percent over former US Rep. Jason Lewis (R).

In May, Harper found Sen. Smith posting a 46-35 percent advantage over Lewis. After this release, Public Policy Polling forecast a 48-39 percent split toward the end of July. Lastly, Emerson College published what appears to be precursor data to the latest Harper findings. The Boston-based university poll (Aug. 8-10; 73 likely Minnesota voters) found a three-point split between the two contenders, 48-45 percent, again in Sen. Smith’s favor.

To the southeast of liberal Minnesota, in conservative South Carolina, veteran Sen. Lindsey Graham (R) has also fallen into a competitive contest with former state Democratic Party chairman Jaime Harrison, who had raised an incredible $29 million for his smaller state race through the end of June.

The most recent poll we have seen from the Palmetto State was released at the beginning of August. Quinnipiac University (July 30-Aug. 3; 91 registered South Carolina voters) detected a 44-44 percent tie between Sen. Graham and Harrison. From mid-July through the beginning of August, six surveys were conducted, including the Quinnipiac study, and Sen. Graham’s average lead was only 2.8 percentage points.

The Wild Polling Spectrum

By Jim Ellis

July 27, 2020 — We’ve seen a plethora of presidential state polls released in the past couple of days, and the results seem to swing wildly among the various pollsters. While most studies have shown former vice president Joe Biden at present winning most of the key states, his margins don’t seem particularly secure even while his national numbers appear stronger.

Let’s explore the polling divergence, and remember that sample selection, weighting, size of the respondent universe, and length of time to complete the survey process are all important variables in determining a ballot test result. Also, the huge number of people refusing to answer their phones or not participating in political surveys means that pollsters must further rely on weighting and mathematical supposition to compensate for the lack of live responses.

With that short background, let’s look at some of the key states producing the widest swings:


FLORIDA

• Quinnipiac University – July 16-20 (924 registered voters; live interview)

Biden 51
Trump 38
Biden plus 13

• St. Pete Polls – July 13-14 (3,018 likely voters via automated system)

Biden 50
Trump 44
Biden plus 6

Though Biden is up in both polls, the margin difference is stark. The Q-Poll, brandishing such a wide spread in what is typically a close political state raises reliability questions.


GEORGIA

• Garin Hart Yang Research – July 9-15 (800 likely voters)

Biden 47
Trump 43
Biden plus 4

• Spry Strategies – July 11-16 (701 likely voters; IVR)

Trump 49
Biden 46
Trump plus 3

Here we see two different leaders within two different polling samples within the same virtual period. Republicans tend to under-poll in the southern states, which could certainly be present in at least the GHY poll.
