After 100 days of political chaos and economic shock that have sent his approval ratings tumbling, Donald Trump hopes to regain the unqualified adulation of his supporters Tuesday at one of his bread-and-butter events: a public rally.

To mark the symbolic milestone in his second term, the Republican US president is visiting the site of one of his last campaign events, in Michigan, a battleground state that swung his way in November’s election.

“The first time, I had two things to do -- run the country and survive; I had all these crooked guys,” he said in an interview with The Atlantic magazine, referring to advisors and cabinet members whom he considered incompetent or disloyal lieutenants in his first term.

“And the second time, I run the country and the world,” he crowed, adding “I’m having a lot of fun.”

Many of the former real estate tycoon’s voters remain behind Trump.

“He knows what he’s doing,” Karen Miner, a 57-year-old wine store owner in Reno, Nevada, told AFP.

“So far, I’m very satisfied with the job he’s doing,” said Frank Tuoti, a 72-year-old retired machinist from New Hampshire.

But he concedes that the tariff instability has made him “a little concerned about the economy.”

Now surrounded exclusively by loyalists, Trump since January 20 has unleashed in terms of tariffs, foreign policy -- and political revenge.

In the grand entrance hallway of the White House, he has moved a portrait of Barack Obama, America’s first Black president, to make way for a painting of himself surviving an assassination attempt.

And in the Oval Office, pushing the limits of presidential power, the Republican has already signed over 140 executive orders.

In the process, he has called birthright citizenship into question, attacked universities and law firms, rolled back environmental policies, entrusted his mega-billionaire ally Elon Musk with dismantling large parts of the federal bureaucracy, and launched a protectionist trade offensive against much of the world -- before partially retracting it.

Many of his executive orders have been blocked by judges, with whom the executive branch has engaged in an unprecedented bout of arm wrestling.

Trump, whose political career was built on deepening divisions, cannot claim the high approval ratings that generally accompany the first 100 days of a US president.

Opinion polls have been unanimous in noting a particularly sharp slide in his approval ratings, fueled by concern about tariffs and his attacks on the institutional order. According to a poll published Sunday by the Washington Post and ABC News, only 39 percent of Americans approve of how Trump is conducting his presidency.

With the exception of Bill Clinton and now Trump, US presidents dating back to Ronald Reagan have had an approval rating topping 50 percent after their first 100 days in office, according to the Pew Research Center.

Trump called the polls “Fake News” in a Truth Social post on Monday. “We are doing GREAT, better than ever before”.

At least 64 percent of respondents said Trump is “going too far” in his efforts to expand presidential powers.

It is impossible to know how long Trump, who at 78 is the oldest US president ever elected, will maintain his frenetic pace.
