May 12, 2020 — On Friday, the most recent Massachusetts Senate Democratic primary poll was released, and it presents a very different conclusion to the close race results previously published.q
Late last week, we covered a University of Massachusetts at Lowell poll (April 27-May 1; 1,000 registered Massachusetts voters, 531 likely Massachusetts Democratic primary voters) that found Sen. Ed Markey (D) locked in a virtual dead heat (42-44 percent) with Rep. Joseph P. Kennedy III (D-Newton) in their intra-party fight.
Emerson College (May 5-6; 740 registered Massachusetts voters, 620 likely Massachusetts Democratic primary voters) conducted a statewide Massachusetts poll on the heels of the UMass effort and sees Rep. Kennedy crushing Sen. Markey, 58-42%.
The focal point of the Emerson poll was the presidential race and reaction to COVID-19, so just one question was asked about the Senate race. Unlike the UMass survey, Emerson did not release segmentation figures for the Senate ballot test question, so it becomes more difficult to judge reliability.
Since the two polls are so far apart, questions arise as to which is the more accurate. The sponsors are known pollsters who regularly survey Massachusetts – Emerson College is located in Boston, while the UMass affiliate resides in Lowell – so neither has a particular geographic familiarity advantage over the other. The sample sizes are both large enough to render strong results, and each has accurately depicted the state in previous studies.
