We start with the correction. On 16 September we published a piece saying Fred Wellman would run in November on the friendlier 2022 lines, and that the pending appeal was unlikely to disturb that. The 8th Circuit disturbed it on Monday.

The court ruled that November’s election must use the same districts as the 4 August primary, which means the 2025 map that Republicans drew at the president’s urging. It then stayed its own order until 5 p.m. on 28 September, so opponents can ask the Supreme Court for relief. People Not Politicians, the campaign behind the referendum, says it will do exactly that.

So nothing has changed yet. Ballots went out to overseas voters on Friday under the 2022 map, and absentee voting opened on Tuesday under the same lines. If the stay expires without the Supreme Court acting, Missouri will be switching congressional districts while people are already voting.

The panel’s reasoning is narrow and it does not depend on partisanship. Voters chose nominees in August under one set of lines. If the general election runs on different lines, the court held, some voters will have picked a nominee they cannot then vote for, while others will have had a say at both stages. That, in the panel’s words, means some Missourians would have more say than others about who represents them in Congress.

The opinion cited estimates that more than 1.4 million Missourians could not vote for the nominees appearing on their November ballots, and that more than a quarter of a million people who voted in August cast ballots for candidates who now cannot represent them. The judges also blamed the confusion on the state court rather than on the legislature or the referendum.

Two of the three judges were appointed by Donald Trump, and the third by George H.W. Bush. Their order directs the district judge to enter a permanent injunction barring any map except the 2025 plan. He entered it the same evening, with the one-week pause attached.

None of that overturns the Missouri Supreme Court, which ruled on 3 September that the referendum petition suspended the 2025 map under state law. The two courts now simply disagree, one about state law and one about the federal Constitution. That is the kind of conflict the Supreme Court exists to settle, and it has already stepped into this case twice.

Wellman is the Army veteran running against Representative Ann Wagner in the St. Louis suburbs. Our piece last week explained why the 2022 lines helped him. They drop the rural territory the 2025 map attached to his district, including the Jefferson County precincts where his primary rival beat him outright. Cook Political Report moved the race from Solid to Likely Republican on 11 September, after the 2022 map appeared settled.

If the 2025 map returns next week, all of that reverses. He goes back to running in the seat Republicans drew to make Wagner safer, with six weeks left and ballots already printed. The rating logic that produced Cook’s move would reverse with it.

He would also be campaigning in a district whose voters have now been told four different times which lines apply. That is not a small problem for a challenger who needs voters to know who he is and which race he is in.

Lennon was describing what a late switch means at the county level. New ballot styles, reprogrammed machines, a new print order, and all of it while absentee voting is under way. She had already tested her tabulators on the 2022 map and planned to mail a thousand ballots on Tuesday.

Our reasoning last week was that the Supreme Court had blocked the district judge’s order on 10 September, so the 8th Circuit had little room to move. That was a misreading. The Supreme Court’s stay was explicitly temporary, tied to the disposition of the appeal, and the appeals court said plainly at its hearing that it believed it had been told to decide the case.

We also leaned on what the lawyers told reporters. The referendum campaign’s attorney called the matter settled, and the state’s attorney general said she saw no path to anything but the 2022 map. Both were reading the same tea leaves we were. That is a reminder to attribute predictions rather than adopt them, and we will be stricter about it.

The 16 September piece stands as published, with this article as its correction. Its account of the primary, the money and Wellman’s record is unaffected. The conclusion about which map he runs on is now in doubt.

Almost nothing, and that is worth stating. Wellman’s service record did not change on Monday. His district may have. This site argues that military service helps Democrats win general elections, and a map fight is the clearest example of a force that swamps any candidate quality, good or bad.

There is a version of this that flatters our argument, and we should resist it. It goes like this: veterans are used to plans changing, so a candidate who spent 22 years in the Army is better equipped to absorb a district that changes shape in October. That is a nice line and it is untestable. We have no evidence that adaptability under fire transfers to ballot access problems.

The honest read is simpler. Republicans drew a map to beat a Democrat in Kansas City, the courts have spent a month arguing about it, and a veteran in suburban St. Louis is one of the people whose race hangs on the outcome. His biography is not the variable here.

One thing Monday’s order did not touch is the referendum itself. Missourians still vote on 3 November on whether to keep the 2025 map for future elections, because the state Supreme Court put that question on the ballot. So Missouri could elect a delegation under a map its own voters reject on the same day. That is an odd sentence to write, and it is where this stands.

People Not Politicians has until Monday to get a stay from the Supreme Court. If the justices grant one, the 2022 map holds and the referendum on the 2025 plan still appears on the November ballot. If they do not, county clerks start over with six weeks to go, and Missourians who have already voted may be asked to vote again on new ballots.

We will follow it either way, and we will flag any further change to the Wellman piece as it happens. Meanwhile the lesson for this site is not about Missouri. It is about how confidently we wrote a sentence about a court we had not heard from yet.
