"That’s not to say the president hasn’t had successes or made progress in changing the course of policy in the aftermath of the administration of President Barack Obama. He signed a huge tax cut. The economy is in good shape, unemployment is at a low level, and the stock market, despite some recent downs and ups, is well above what it was when he came into office.
He has changed the enforcement of immigration laws, as he promised during the campaign. He has softened or reduced regulations on businesses. He has facilitated a conservative shift in the makeup of the federal judiciary. He has pulled the United States out of the Paris climate agreement and sought to shift U.S. trade policy away from the free-trade consensus of past administrations.
Those changes cannot be underestimated, and to the degree that he has been stymied or unsuccessful elsewhere, many of his supporters blame the Democrats, congressional Republicans or the federal bureaucracy, a.k.a. the deep state. The core of his support remains intact, and he is the most popular person in his party by a mile."
