You are seriously delusional if you think one person in the span of four or eight years if he's lucky is going to roll back all the damage that's been done.
It won't happen overnight, but the things that matter, the foundational elements so critical to maintaining an ongoing campaign of restoring the Republic, can set things on the right track. It has taken nearly 60 years to go from having some invasive socalist elements to full metastisization, and the cleanup won't happen overnight.
It will take the purging of the bureaucracy of socialist elements and personnel who advocate unconstitutional and extraconstitutional actions on the part of those departments which have subverted the Republic, it will take massive reductions in Federal internal power and scope and the restoration of the States as sovereign political entities, and education of the American voter as to just what the FedGov is and isn't supposed to do (Civics).
While all those subversive elements out there have a Right to speak their piece, they do not have a right to riot in the streets, trespass on or destroy private property, nor shout down those who disagree.
Doing it right will take a little more time, but will leave a Republic that is faithful to its own architecture and axioms, where going outside the authority therein would, in and of itself, subvert the very ideals and principles the Republic was designed to safeguard. The means make a difference, too.
It didn't get messed up overnight, despite people becoming aware of it more suddenly, and it will take longer to reverse the damage. Unfortunately, unlike Conservatives, those adversarial to the Republic have no normalcy bias ('cause they ain't normal), and will fight for every edict, and every word and paragraph they have managed to undermine.
