A Polling Comparison

By Jim Ellis

Neck-and-neck polling in a few key battleground states between President Donald Trump and former vice president Joe Biden shows interesting parallels to the 2016 race between Trump and Hillary Clinton.

Sept. 10, 2020 — With a plethora of presidential polls being released every week providing sometimes radically diverse results, it is often difficult to draw a clear picture of where the electorate is heading.

The conventional wisdom and preponderance of polling trends suggest that Joe Biden is leading the presidential race, but that President Trump is making a comeback, and the race is beginning to show some of the same characteristics found in 2016.

Three of the key states that baffled the political pollsters four years ago were Michigan, Pennsylvania, and Wisconsin. As we will remember, President Trump was expected to lose them all but scored close upset victories in each place.

The aggregate group of 2016 pollsters missed in each of the three states and the Real Clear Politics polling archives still publicly maintains all of those survey results. Therefore, we have the historical data to draw clear parallels between then and now.

In Wisconsin, 33 polls were taken during the election cycle and only one, from the Trafalgar Group at the end of the campaign season, placed Trump in front. A total of 62 polls were conducted in Pennsylvania with only three, again including a Trafalgar poll, projecting the future president into the lead. In Michigan, 42 polls were publicly released with Trump ahead in just two.

Though it is not generally statistically significant to average polling results because the polling methodologies, and certainly sample sizes, are very different, doing so does give us a guide as to the error factor that was present in 2016, and possibly a glimpse into what might exist this year.

In Wisconsin, the average Hillary Clinton lead advancing into the general election was 6.5 percentage points. With a 0.7 percent win for Trump, the overall error factor became a whopping 7.2 percent. The Pennsylvania numbers were closer but still a significant miss. Clinton’s average lead heading into Election Day was 2.1 percent and the president won there by the same 0.7 percent that he carried Wisconsin. Therefore, the Keystone State error factor was 2.8. Michigan was a similar story. Error factor: Clinton plus-3.6 percent. Trump victory margin: just 0.3. Total Michigan error factor: 3.9.

Is Biden Under-Performing?

By Jim Ellis

Former vice president and current 2020 presidential candidate, Joe Biden (D)

May 28, 2020 — Currently, former vice president Joe Biden is leading in virtually every battleground state poll that has been released into the public domain; but do the survey numbers tell the whole story? Other available data, that derived from actual votes being cast, suggest there may be cracks forming in his political armor.

In terms of battleground states, a new Arizona poll was released Tuesday, in what could become the most important must-win domain for the Trump campaign. There, the Phoenix-based HighGround Public Affairs consulting firm publicized their latest Arizona statewide poll (May 18-22; 400 likely Arizona general election voters), and the ballot test projects Biden holding a tighter 47.0 – 45.3 percent edge over President Trump.

Though Biden leads, the trend is a clear improvement for Trump since the OH Predictive Insights poll (May 9-11; 600 likely Arizona voters) became public during mid-May and posted the former vice president to a 50-43 percent advantage. Redfield & Wilton Strategies followed with their survey release (May 10-14; 946 likely Arizona voters) that yielded a closer 45-41 percent Biden lead.

Tuesday’s HighGround survey also published some interesting secondary questions. In answering whether the respondents felt President Trump job performance was excellent, very good, or OK, the combined positive calculated to 49.5 percent. Among those believing the president’s job performance is poor or failing, the negative totaled to 49.0 percent.

Accordingly, 29.3 percent of the Arizona respondent sample believes President Trump is to blame for the spread of the coronavirus, while 20.3 percent pin the responsibility on China. All other responses: the people, federal government, Democrats, or other unnamed sources each registered less than 10 percentage points. A total of 25.3 percent say they either don’t know or believe no single source is to blame.

Over the Memorial Day weekend, the state of Hawaii hosted its Democratic presidential primary. The unique format is interesting in that there were two votes the participants cast: the first included choosing among all of the names who originally qualified for the Hawaii presidential nomination ballot. The second isolated only Biden and Sen. Bernie Sanders (I-VT). Just under 35,000 people cast mail votes in the stand-alone presidential primary.
