There is no mechanism for citizens of the united states to recall a president or member of congress. They must wait 2, 4, and 6 years depending on who they'd like to replace. This contributes to the the current woes as as many members of congress and some presidents (like this one) would certainly undergo recall battles or be immediately recalled. Since we can't though, and elections in this country are a 12-16 month barrage of lies, propaganda and ads by the time voting does come around people just check which ever box matches their team, zero thought given and are thankful the whole mess is over with so they can mostly ignore politics until its time to start complaining again about how poorly they're represented. Repeat.

About 30% of our electorate consists of so-called "deplorables" who are geographically distributed in a way that gives them outsized influence. The deplorables were happy to set aside their own best interests at the voting booth because Trump promised to hurt other people more.

Promises were made, and as far as the deplorables are concerned, promises were kept. They continue to approve of his actions wholeheartedly.

There is probably no way back for us, unfortunately. Please keep in mind than a healthy majority of American voters either voted against Trump or chose to sit out the election. We are largely powerless, though, due to system-level weaknesses that have been present since the nation's founding but couldn't effectively be exploited until recently.
