(FILES) US President Donald Trump walks off Air Force One after arriving in Orlando, Florida, on March 3, 2017, before heading to St. Andrew Catholic School. While the new US president has shown a capacity to change, both his tone and his positions, he has been unable to show the world a "new" Trump, with a steady presidential style and a clearly articulated worldview. As the symbolic milestone of his 100th day in power, which falls on April 29, 2017, draws near, a cold, hard reality is setting in for the billionaire businessman who promised Americans he would "win, win, win" for them. At this stage of his presidency, he is the least popular US leader in modern history (even if his core supporters are still totally behind him.) / AFP PHOTO / NICHOLAS KAMM / TO GO WITH AFP STORY, US-politics-Trump-100days
