When Trump and Hillary competed for the presidency, why was Trump, who had no political experience, selected?

Because Trump impressed the middle and lower classes in the United States. Hillary protects the interests of the wealthy class in the United States, which is why Trump won the presidential election. After all, the number of middle- and lower-class people in the United States is much larger than that of the wealthy class, which means that US President Trump's votes are much higher than Hillary's. So we now see that the people who oppose US President Trump are mainly from the wealthy class, because Trump’s governance policy has harmed the interests of these wealthy classes. That’s why the impeachment of U.S. President Trump has only recently occurred, mainly because the resentment of the wealthy class against U.S. President Trump has accumulated to a certain extent.

U.S. President Trump has indeed made outstanding contributions since taking office. By launching trade wars against other countries, some large American companies have returned to the United States, which has caused some middle- and lower-class Americans to return to the United States. Got a lot of job opportunities. This has also made US President Trump's reputation among these middle and lower class people become better and better. Of course, this has also harmed the interests of some wealthy people, because returning to the United States will increase the production costs of these companies.

The President of the United States has also vigorously cracked down on illegal immigrants at the US-Mexico border and drug traffickers in Mexico. The President of the United States has prevented illegal immigrants from Mexico from entering by building a wall on the US-Mexico border. This method has also prevented Mexican drug traffickers from entering the United States to a certain extent. This also safeguards the safety of life and property of the American people, so US President Trump has indeed been highly praised by the American people in this regard.

Furthermore, US President Trump did not launch any military operations during his term, so this also made the American people very happy. Because anti-war sentiment in the United States is very high now.
