Trump became the 5th U.S. president elected while losing the popular vote. He did so backed by a base that was fanatically loyal and ideologically intransigent. Trump is stuck on the horns of a dilemma: The more he caters to his ideologically rigid base, the more he usually alienates the rest of the country. But the more he reaches out to compromise with the other side, the more he is called a sell-out and traitor by his ideologically pure base.
That leaves a skilled and seasoned politician very little room to operate. Trump is proudly not a politician. Now that Democrats control the House, Trump is dealing with a major part of the legislative branch that does not think of Donald Trump as their boss. As a narcissist who had nearly dictatorial power in the running of his own company, this situation is not in his wheelhouse.
Trump has great instincts for ginning up his base, but those instincts do not serve him well when trying to reach out to others. The 2018 midterms were a case in point, with Trump sending troops to the border. To his supporters he sold it as stopping
the foreign hordes, to his detractors he sold a compassionate conservative version of 'just say no', a wall whose very existence would prevent thousands of Central Americans of ever attempting the journey.
Ann Coulter talked and Trump listened. We got a 35 day government shutdown as a result. Even Trump is not suicidal enough to pull the shutdown card out again, so now it's sign the legislation but declare a national emergency.
What will probably happen is that Trump's wall end, not with a bang, but in the dry language of a Supreme Court ruling. The one thing that gives me pause is the language of the
National Emergencies Act does not define a national emergency. The President can say that an emergency is what is says it is, because there is no limitation on his power under the statute. However, I'm not sure the Courts are going to give the President carte blanche, especially when he said "I don't have to do this" when announcing the State of Emergency.
