Conservatives have long hated the State of the Union. We prefer a small, modest government, and to us the State of the Union has too many trappings of monarchy. The president stands above the Congress and the Supreme Court, telling everybody what to do. That is hardly a fit model for a republic. Many liberals, who now must endure being lectured for an hour by Mr. Trump, have also come around to the view that this annual event should cease to exist.
