Be prepared to end any state of emergency Trump may declare upon entering office. If President Biden sees no reason for a national state of emergency, the reason Trump would institute one is for the power, no valid reason.
If I was president and wanted to declare a national state of emergency, hated every minority in the USA, and was a religious bigot; I’d declare the emergency at the southern border. That would give the president the right to order a round up anyone be felt was a threat and deport and/or imprison them. Texas has a lot of room for big internment camps.
