What are you basing that on?
I've written at length on the subject on this forum.
Trump was the dad-gum President of the United States for 4 years and he barely used his power because he doesn't care about power. He only cares about status. He stirred out of bed at 9 or 10, got on his big boy pants and went to the Oval Office. He had the right to the most complete and secure briefing on the events of the world and he asked them to make it shorter and then stopped bothering with it many days. What he did the next few hours is anyone's guess. Then he spent the afternoon and evening on Twitter and yelling at his TV.
He signed the tax cut that the mainline GOP wanted. He didn't sign any legislation that was his idea. He had promised to end all the wars, but the best he did was get a schedule for Afghanistan to end soon after he left office. He had promised a big infrastructure bill, but never even announced the bill itself. He had promised to replace Obamacare with something much better, but 8 year later he still has only a concept of a plan. He went to play golf almost every weekend. He is SO lazy.
Trump ran for President to promote his brand. He didn't think he would win the first time. He spent 4 years puttering around to the events he was told to go to and saying dumb stuff that the other people in the meeting tried to ignore or redirect. He didn't accomplish any Presidential things at all. Then he ran for reelection, because that's what President's do and he LOST. He is a narcissist and cannot stand humiliation. He has spent 4 years demanding vindication for it and now he's got that. He'll go back for 4 more years and then he'll retire.
I know he doesn't want to be President for life because he didn't bother being President when he WAS President. I am not AT ALL saying he is harmless. He did harm and he will do harm again. But he won't seize dictatorial power, not just because of the checks and balances, but because he doesn't want all that hassle. He won't utterly destroy the economy because his influence is limited. He will continue to erode public trust in institutions. He will continue to embolden racists and misogynists and trans-phobes and whatever brand of haters. He will continue to race bait and racial scapegoat. He will probably all but abandon Ukraine. He will not even tap Israel's brakes. He will tell 40 lies every day, some big, some small. He will probably add tariffs and will drag down our economy some. He will deregulate business, which will be good for the stock market, and bad for workers and the environment and really bad for a few companies who use the whole rope he gives them and accidentally hang themselves. He will pave the way for JD Vance to continue behind him. He will show my daughters that the leader of the country can be uselessly mean. It's bad stuff and it didn't need to happen, but it will be recoverable.
But in 4 years, he won't want to stay.
