But in addition to consistently exhibiting what many see as negative attributes, Trump has also tried to keep his biggest campaign promises on repealing Obamacare, securing the border and cutting taxes, and he stayed true to his word with his pick of Neil M. Gorsuch for the Supreme Court. Now, his declaration of U.S. recognition of Jerusalem as Israel’s capital fulfills another pledge. No one who backed Trump as a candidate, with all his flaws, has been given much reason to abandon him.

Liberals seem to think the tax bill and other administration priorities will wake Trump country to the phony populism of its champion, but Trump’s voters always understood that business was going to benefit from having such an avowedly pro-business president. Really, the only supporters who might have cause for disillusionment are those who argued, or hoped, that once he assumed the presidency Trump would “pivot,” becoming “more presidential.” But that would probably be the one act that would cost Trump his base.
