GOP Interests undefeated in close cases in John Roberts' "nonpartisan" Supreme Court

In 5-4 cases, GOP donor interests are 73-0. That's a good record for an apolitical body. Can somebody do a standard deviation thingy to let me know if that's a coincidence?

Seventy-three of these decisions are marked by a few characteristics: One, it’s 5–4, they haven’t tried to get a real majority, just a bare majority. Two, the 5–4 breaks along partisan lines. And three, there’s a big Republican donor interest at stake. There are 73 of those cases, and 73 for 73, the big Republican donor interest won.

I think the first thing is to highlight the record. Most Americans have no idea that under Chief Justice Roberts, there are 73 of these 5–4 partisan decisions in which there was a big Republican donor interest implicated. And in 73 out of 73, the big Republican donor interest won. I think that’s a piece of evidence that, if we were bringing a discrimination or bias case to a jury, would very compelling to that jury. And the American public is the jury in this conversation, and they’ve got to be shown that evidence so they understand what’s going on.
