Trump had no plan, that was just another one of his many lies. Republicans do not want to cover everyone.
Republicans have spent eight years fooling themselves about Obamacare. They have built a news bubble that relentlessly circulates exaggerated or made-up news of the law’s shortcomings and systematically ignores its successes. The smartest members of the conservative-wonk set played a more clever game to retain their influence. No serious conservative analyst could argue that Obamacare had actually made the health-care system worse. How could they, when the federal government is now spending less money on health care than it was projected to spend before Obamacare passed, medical inflation is at the lowest level since the government began recording it 50 years ago, and 20 million more Americans have insurance? But admitting Obamacare constituted an improvement in the health-care system, even an imperfect one, would be tantamount to expulsion from the conservative movement, and with it any hope of influencing Republican policy. The closest they might come is pleading that repealing Obamacare was “not enough,” that they must also replace it with something better. This formulation allowed them to neatly sidestep the question of whether repeal alone would make the system better or worse.
So instead of comparing Obamacare to what it replaced, they compared it to the plan Republicans would have passed, if only they had the chance. The existence of the mythical Republican health-care plan was the foundation for every serious critique of the law. And now that that plan has finally appeared, virtually the entire conservative intelligentsia has been forced to admit it is worse than Obamacare. The single data point that conservatives have repeated with the most relentless frequency is that Obamacare is unpopular. It is true that, for most of its life, the law has polled in the 40s. Republicans deemed all disapproval of Obamacare to be approval for their stance, never acknowledging that much of this disapproval came from those who wanted the law to do more, not less. Now that there is a Republican alternative, it is polling at an astonishing 17 percent. Comically, repeal efforts have pulled Obamacare’s polling above water. The slim reed of public opinion upon which they built their manic repeal crusade snapped immediately under the weight of political implementation.
Other than cutting healthcare and allowing insurance companies to again write policies that don't cover anything if you need care. The republican plan would transfer federal funding from helping low- and middle-income Americans get health care to tax breaks for high-income Americans and health care special interests.
