Donald Trump's approach to politics appears to have shifted. Initially, his rise in 2016 was described as "populista" as he positioned himself as a rebel challenging the system on behalf of ordinary Americans. However, this approach has largely been abandoned. Recent polls by Reuters and Ipsos show Trump's approval rating has fallen to a historic low of 33%. This means only about one in three Americans approve of his performance. The percentage of those who "firmly" approve of him has also been declining.
Further details on Trump's changing political stance and the polls are available. The shift in his approach has been notable, with some characterizing him as having become "antipopulista".
