I do not think it is an ideal situation by a long shot. It' s not as bad or as dangerous however as living under a judicial tyranny, where random district court judges can interfere in crucial and complex national security matters.
This judge went looking for a fight or more likely headlines. Prudence would have dictated not seeking out a direct confrontation with the Executive Branch. A TRO properly issues only in situations where preserving the status quo is necessary to prevent irreparable harm. Forcing a few immigrants to wait a few days or weeks to get on welfare is not irreparable harm. It certainly is not irreparable harm to the parties, the states of Washington and Minnesota. Any direct harm to them is speculative and de minimus.
Any judge is too politicized when their judgements don't fit with your politics. When they do, they are always prudent and judicious.
Due process, checks and balances.
When your argument goes to the point of suggesting North Korea might not be as bad or as dangerous, then you really don't have an argument.
