Minnesota getting a representative from the place where all the inbred ICE dipshits come from is just the first step of reparations.

Trump’s Census Proposal to Exclude Some Immigrants Could Cut Seats From Red States
A Trump administration proposal to block some immigrants from the 2030 census could shift congressional seats away from Republican states, a New York Times analysis found.

Senator Roger Marshall is up for re-election (gift link) www.nytimes.com/2026/09/08/u...
It was Easter weekend in 2007 when a police car pulled up to Joe Vasquez’s home in rural Kansas.

A doctor had filed a lawsuit against him and his wife over an unpaid $4,561 bill from her emergency hysterectomy three years earlier. They had missed a court date, and the doctor’s lawyers asked the court to issue an arrest warrant.

The police took the couple into custody as their grandchildren prepared for an egg hunt, Mr. Vasquez said. They spent two days in jail before their son could borrow the money to post bond.

“We had no money to pay,” said Mr. Vasquez, now 68. At the time, his wife was working at a manufacturing plant and he was on disability, he said.

The doctor who sued the couple was Roger Marshall, now a senator from Kansas. Mr. Marshall, a Republican who is seeking re-election this fall, filed lawsuits against more than 700 patients with outstanding bills during his decades-long career as an obstetrician-gynecologist, according to a New York Times analysis of Kansas court records.

I still think DP was a horrible mistake. I truly hope in the post-Trump era we return to sensible, targeted disclosure control for tabular data, and do not reinstate DP just because deluded conspiracy theorists hate it.

What I meant was that in the final implementation of 2020 DP the epsilon was so high that the noise infusion had only minor consequences for usability. But it is truly crazy paranoid to think that any version of DP was biased against Repubs. More here: pubs.aeaweb.org/doi/pdfplus/...

I argued in the Journal of Economic Perspectives that DP was a huge mistake for the Census and I hope we do not go back there. But you have to be seriously stupid to think that DP is somehow biased against republicans. www.aeaweb.org/articles?id=...

I also said that DP in the 2020 Census was an overwrought response to a non-existent problem and should never have happened. That part didn't make it into the story. 2/2
