Anything that is visible , or that can be made visible, can be taken to the courts.
For example, Some of Trumps non wall related Immigration initiatives which are reasonable and authorized by statute are currently tied up in the courts. I would rather have those things delayed or even blocked than create a new executive loophole for the left leaning dem who will eventually occupy the WH again sooner or later. Our system is designed to default to making it difficult to get things done for a reason.
The WH changes hands - it is “the cycle of life” so to speak. Trump has a good chance of being re-elected but if he is a Dem is sure to follow. We need to plan accordingly but it’s normal. Trump is no prize but the office has endured worse.
My concerns are the long term plans one party has to put their thumb on the scales and via things like unchecked immigration, resulting fraudulent census numbers and elimination of the electoral college subverting our constitutional republic, replacing it with perpetual one party rule like we see in CA. That is a recipe for a Balkan style shooting war.
