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.

Progress Michigan’s Lake Effect newsletter: “The governors’ approval ratings pertaining to the [coronavirus] crisis are better than those of the president.”
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.

Jan. 3, 2020 — The Census Bureau just released its new population growth estimates for the 12-month period between July 1, 2018 and July 1, 2019. Their data allows us to assess just which states will likely gain and lose congressional districts in 2020 reapportionment, both in terms of the real numbers just presented and for projecting the final count once the decade’s final-year patterns are calculated and the census is actually conducted.
Nov. 12, 2019 — The Cook Political Report in conjunction with the Henry J. Kaiser Foundation of San Francisco sponsored a four-state survey, called the “Blue Wall Voices Project,” covering key Great Lakes states to determine Democratic presidential primary standing within the region among other issues.
In the two North Carolina special elections that were decided on Tuesday night, the winning Republican candidates exceeded the published polling projections. The same pattern also occurred in Pennsylvania back in late May when Rep. Fred Keller (R-Middleburg), while predicted to win comfortably, garnered a considerably larger vote percentage than projected when he scored a 68 percent special election victory.

June 25, 2019 — There have been several important state polls recently released that provide us data about where the Democratic presidential candidates stand in relation to popular preference. But that is only half the story.
