April 6, 2020 — Polls were just released in both Michigan and Wisconsin, obviously two critically important states that will weigh heavily in determining the final outcome of the next presidential election. While it’s too early to take any general election poll as a true projection of what may happen in November, particularly in light of the current unique situation, the survey did reveal some interesting points.
Public Policy Polling tested the Michigan electorate for the Progress Michigan progressive left organization (March 31-April 1; 1,01 registered Michigan voters) and Marquette Law School just completed their quarterly survey of Wisconsin voters (March 24-29; 81 registered Wisconsin voters). Both made public their results.We won’t pay too much attention to the ballot tests because it is so far away from the actual vote and the political situation is obviously going to change during the coming months, but the two pollsters found President Trump and former vice president Joe Biden within the margin of error in each state. In both cases, it was Biden who enjoyed a three-point lead.
Within this prism, it is important to recall the 2016 race in which polling badly underestimated Trump’s strength against Hillary Clinton in these two places. According to the 270 To Win organization, which tracked polling throughout that election year, the final averages going into the final weekend found Trump trailing by six points in Michigan and seven in Wisconsin. He won each state by approximately one percentage point, thus proving a large error factor in virtually all of the late polling.
A post-election analysis in which the Pew Research Center and CNN participated, among other firms and media outlets, concluded that a major reason for the flawed projections were the much larger number of Democrats willing to respond to the polling questions than Republicans. Even understanding this was the case at the time, the pollsters’ weighting formulas and algorithms still badly missed the mark throughout the crucial Great Lakes region.
