I did not expect the backlash to come so quickly but I think Trump will ride it out in the short term. He will easily rebuff or delay the legal issues and I think the foreign policies will have little effect on the populace as Americans are generally ignorant of the rest of the world. I think it will be the economy that ultimate brings the Republicans down.
This from the ABC article I linked to. Trump isn't being allowed to ride roughshod over all of the constitution and judiciary.
"With Trump signing more than 75 executive orders since taking office, the unprecedented flood of litigation has yielded mixed results in blocking the president's unilateral efforts to reshape the federal government. His attempts to freeze funding or rewrite longstanding laws have generally been blocked, but some federal judges have implicitly given him the green light to carry out part of his plan to reshape the federal workforce.
U.S. District Judge John Coughenour -- who was nominated to the bench by Ronald Reagan -- handed the Trump administration one of its first legal defeats by blocking Trump's executive order on birthright citizenship and offered one of the fiercest criticisms of his presidency's early actions.
"It has become ever more apparent that to our president, the rule of law is but an impediment to his policy goals," Judge Coughenour said. "There are moments in the world's history when people look back and ask, 'Where were the lawyers, where were the judges? In these moments, the rule of law becomes especially vulnerable. I refuse to let that beacon go dark today."
