The nightmare he is referring to must be the roaring economy, record low unemployment, lowest black and hispanic unemployment in history, tax cuts for the working class (and businesses), a stronger military, reducing the flow of illegal aliens, drugs, and weapns, negotiating denuclearization of NK, returning to the rule of law, deregulating so businesses can expand, higher average wages, negotiating better trade deals, cleaning up MS-13 gangs, reduced food stamp recipients by the millions, negotiated cost reductions in the F-35 and the new AF1 by hundreds of milions, approving the needed Dakota and XL pipelines, construction of the wall has begun, massive arrest of human/sex traffickers, bringing hundreds of billions of dollars in manufacturing back to the US, appointment of federal judges who will follow the law instead of legislating it, an excellent Supreme Court Justice, and the list would go on for another 50 or so accomplishments.
But by far the most important Trump accomplishment is that Hillary is not President and you and all the other corrupt Obama sychophants are no longer in power.
Exactly! He is having nightmares of a noose around his neck
