The “blue wall” once referred to a group of Northeast, Midwest, and West Coast states that, conventional wisdom said, “always vote for Democrats.” Unfortunately for Democrats, that was wrong, and in 2016 Donald Trump shockingly won three “blue wall” states — including, narrowly, the state of Michigan.

It maybe shouldn’t have been such a shock, though. All three of the “blue” states Trump won actually had a history of electing Republicans at the state level. Michigan in particular had been fully taken over since 2010 by Republicans, who then spent years gutting unions, restricting abortion, loosening environmental protections, and generally just turning a Republican policy wish list into law. So Trump winning Michigan was, in a way, just the culmination of a years-long drift to the right there.

But by 2022, something had changed dramatically. In a midterm election where Republicans were favored, Democrats won every branch of elected government in Michigan — governor, state House, and state Senate. The state Senate in particular had not been under Democratic control since 1984. And Democrats got busy using their new power immediately: repealing much of the right-wing legislation of the previous years, passing strong LGBTQ protections, quadrupling a tax credit for the poor, and allocating a billion dollars for the auto industry to transition to electric cars. Suddenly Michigan was cranking out more progressive legislation than almost any other state in the US.

So to recap: Michigan was once a blue state, except it wasn’t actually, and in fact over time it got pretty red, but then it became an actual blue state. (Again?) Or something like that. Obviously, the truth is that Michigan is a swing state. But the story of each of those swings is actually key to understanding how US politics work in the 2010s and 2020s. And it can tell us a lot about our next election, too.

Correction: the timeline incorrectly shows Republicans winning control of the state House in 2006. Democrats won the House that year.

For Michigan election data we drew from two useful websites from the Michigan Department of State. First, they have election results down to the county level going back to the late 90s: https://www.michigan.gov/sos/e....lections/election-re

They also have a tool that produces election results down to the city/township level: https://miboecfr.nictusa.com/c....gi-bin/cfr/precinct_

To show national and statewide exit polls over time, we used NBC News’s data — they’re among the only organizations whose granular exit poll results both nationally and statewide going back a decade are still publicly available.
