Aug. 24, 2020 — The state of Minnesota has been the most loyal of Democratic states in the presidential election since 1972, but the latest survey research data suggests that the northern domain is returning to the competitive realm this year.
Four years ago, President Trump fell just 1.5 percent short of winning Minnesota, thus providing a sign that the electorate was beginning a possible transformation. That was partially underscored in 2018 even when the party lost two suburban Minneapolis districts but gained two back in the rural north and south. The latter two congressional seats were the only ones Republicans converted from Democrats in the whole nation, except for a Pennsylvania seat that flipped to the GOP because of a court-imposed redistricting map that substantially changed the boundaries.
The 2020 Minnesota polls have seesawed. Mason-Dixon Polling and Research was the first to release a statewide poll this year and did so just before the George Floyd killing occurred in Minneapolis. The M-D survey was conducted over the May 18-20 period and yielded former vice president Joe Biden a five-point lead, 49-44 percent. The Morning Consult organization was also in the field during that same relative period, May 17-26, and found a similar spread between Biden and President Trump, with the former posting a seven-point edge.
Within this same period, the Floyd controversy began on May 25. During the next two months, a pair of Minnesota polls were conducted, and Biden’s lead soared into double digits. Gravis Marketing executed a single-day poll on June 19 and found Biden’s lead had grown to 16 percentage points. Fox News followed with their survey a month later, July 19-20, and found a similar 13-point Biden advantage.
The situation began to change when Morning Consult again tested the Minnesota electorate over the July 17-26 period and saw the race closing back into the three-point range. This survey was confirmed with the Trafalgar Group’s numbers derived from their July 23-25 poll that found a similar five-point margin developing between the two candidates.
The next two, however, from Public Policy Polling and David Binder Research, both conducted during the July 22-31 time frame, produced 10 and 18 point spreads in Biden’s favor. The Binder poll, however, utilized a sample size of only 200 respondents, far below what would be typically required for a reliable statewide poll for a domain housing eight congressional districts.
