Our project to calculate the 2020 presidential results for all 435 congressional districts nationwide heads to Michigan, which returned to the Democratic column after another competitive race. You can find our complete data set here, which we're updating continuously as the precinct-level election returns we need for our calculations become available.
After supporting Donald Trump 47.6-47.4 four years ago, Michigan went for Joe Biden by a wider 51-48 margin, and he improved on Hillary Clinton's performance in 12 of 14 districts, with the only exceptions coming in the two bluest seats. Biden carried the same five districts that had supported Clinton plus Democratic Rep. Haley Stevens’ 11th District in the northwestern Detroit suburbs. Trump, meanwhile, carried the other eight constituencies he’d taken in 2016. You can find a larger version of our map here.
Since it's the lone flip, we’ll start with the 11th District, which shifted from 50-45 Trump to 52-47 Biden. This seat also went for Mitt Romney 52-47 back in 2012, which makes it the first Romney/Trump/Biden district we’ve found anywhere in the country. Major outside groups on both sides spent a serious amount of money late in the campaign in the race between Stevens and Republican Eric Esshaki, but Biden’s victory helped Stevens prevail 50-48.
While Democrats had no trouble holding the other five Biden seats, Rep. Dan Kildee’s 5th District was once again competitive at the presidential level. This constituency, which is home to Flint, Saginaw, and Bay City, shrunk from 61-38 Obama to 49.8 to 45.5 Clinton, but while Democrats hoped that it would snap back in 2020, Biden won by an almost identical 4.3-point margin (51.4 to 47.1) this time. Congressional Republicans, though, were unable to take advantage of the area’s drift to the right. Former state Rep. Tim Kelly raised very little, and Kildee handily beat him 54-42.
A different district that had trended the wrong way for Democrats between 2012 and 2016, however, did return to form this year. The 9th District in the northern Detroit suburbs had narrowed from 57-42 Obama to 51-44 Clinton, but Biden carried it by an Obama-esque 56-43 margin; Rep. Andy Levin, meanwhile, won his second term 58-38. Biden also won Rep. Debbie Dingell’s 12th District in the Ann Arbor area 64-34, while he took close to 80% of the vote in both the 13th and 14th Districts in the Detroit area, which are respectively held by Reps. Rashida Tlaib and Brenda Lawrence.
We’ll move on to the eight Trump seats, starting with the only one to elect a Democrat to the House this year. The 8th District in the Lansing region did support Trump again, but his tight 50-49 win was a considerable drop from his 51-44 showing in 2016. Democrat Elissa Slotkin flipped this seat two years ago 51-47 after a very expensive race, and she won by that very same margin this year, albeit in a contest that attracted far less outside money.
Biden narrowed the gap in a few other districts, but his improved performance wasn’t enough to cost Team Red control of any of their seats. The 3rd District in the Grand Rapids area went for Trump 51-47 after backing him by a stronger 52-42 margin; Republican Peter Meijer, though, won the race to succeed retiring Republican-turned-Libertarian Rep. Justin Amash by beating Democrat Hillary Scholten 53-47 after a costly race.
The 6th District in southwestern Michigan, meanwhile, supported Trump 51-47, which was also a drop from his 51-43 victory in 2016. Veteran Republican Rep. Fred Upton, however, again ran well ahead of the ticket and won his 18th term 56-40.
Trump carried the remaining five GOP-held seats by double digits, though notably, his margin of victory was weaker in all of them than it was in 2016. Rep. Jack Bergman’s 1st District in the northern part of the state went for Trump 58-41 four years after backing him 58-37. Meanwhile, Rep. Bill Huizenga’s 2nd District along the western Michigan coast backed the top of the ticket 55-43 after compared to Trump’s 56-38 spread last time. Things were more stable in the 4th, 7th, and 10th Districts, but Biden’s improved share of the vote across the board was key to his victory.
Republicans have enjoyed complete control over the redistricting process in Michigan the last three rounds, but this time will be different. In 2018, voters passed an amendment to the state constitution that creates an independent commission to craft new congressional and legislative boundaries.
