Emergency powers should be reserved for situations where there is broad agreement that the usual rules should be suspended - and never invoked to resolve a political dispute.
Hmm. When was the last time we got "broad agreement" with Nancy and Chuckie on ANYTHING with the GOP? Yeah, I thought so. You can throw that idea right out the door.
Which is why invoking emergency powers would be a mistake, and an abuse of the law.
Trump lost his opportunity on the wall. The voters took if from him by giving the House to the Democrats. He needs to man up and face reality.
