Good points, and I agree that the federal court judges are not meant to represent the electorate for their jurisdiction, they're appointed by the President.
I did just find this article stating the 9th isn't as "nutty" as it once was ->
http://www.mercurynews.com/2017/02/07/how-liberal-reputation-of-9th-circuit-court-of-appeals-is-overblown-scholars-say/And I found another talking about how Arizona wants to leave the 9th district, likely because they're super conservative. ->
https://www.theatlantic.com/politics/archive/2016/02/a-circuit-split/435567/Unfortunately for Arizona and as you say...the court doesn't need to represent the will of their people, only the will of the Constitution.
To the OP...the checks and balances going on right now are good, they aren't being abused. Trump needs to slow the fuck down and make decisions within the bounds of fact-based logic and law. That's how this country works. If he continues to fight it he'll continue to get opposed. We're seeing the system working. (And I'm not saying that because Trump isn't getting his way, I agree with some of his ideas.)
If so, then the 9th district judges represent their district pretty accurately. The West coast (where the 9th district is) is incredibly liberal! Washington, Oregon, California...all super liberal states.
Someone else mentioned that the 9th district should be disbanded. I wonder which country this person is from. Federal court districts aren't disbanded in the US and anyone who thinks they should be is a terrorist to the US.
If the Department of Justices (i.e., Trump) believes they have a better case than the 9th District Appeals Court, they'll escalate the appeal to the Supreme Court. And the Supreme Court is about to have more Republican appointed judges than Democrat appointed judges...so Trump should have nothing to complain about regarding their final decision.
That's how justice works in a Democracy. Full stop.
Frankly, there have been problems before with nutty stuff from the 9th. You are perhaps correct it represents the far left fringe thought of their area, but there is no requirement or benefit from a FEDERAL circuit court to "represent their area." None whatsoever.
However, that is the way it has always been with that court. I'm not complaining or moralizing, just trying to comment on the reality of that particular situation. Many Americans view virtually anything coming out of the 9th circuit court with disgust, skepticism, etc. It's pure comedy.
