The thing I worry about most is what happens when the next Democrat president declares a state of emergency over a school shooting and starts (attempting) to confiscate guns.
That would be akin to calling 911 because McDonald's ran out of chicken nuggets.
A president needs at least a modicum of constitutional cover to declare a national emergency. Trump is on firm constitutional grounding in this case. Hell, he was elected to handle the ongoing national emergency at our southern border.
