How will the court vote on Illegal immigrant Census case?

[Greedo punched first]

I'm thinking at least 6/3 to count everyone, at most 8/1.  Gorsuch is just about a sure thing to oppose the EO, Roberts and Kav don't like to upset the apple cart, and Alito is almost a sure thing to support the changes.  ACB and Thomas are IDK.

Thomas will support Trump. He almost always sides with Alito.

It looks like the case will be dismissed or Trump loses on the merits. Four Republican justices seem inclined to dismiss the case or rule against Trump. Thomas and Alito likely side with Trump. If the case is dismissed, there will be future challenges that Trump will lose in a 7-2 decision.

I can see an argument that illegal immigrants should not be counted because they are not supposed to be in the US?

In theory illegal immigrants are supposed to be arrested on the spot and deported when found out.

I can't see any argument to exclude legal immigrants from counting though.

The constitutional text itself requires that undocumented immigrants be counted. That's why "citizens" and "persons" both appear in the text. The tradition for over 200 years was to have them counted.
