Trump made many promises during his 2015 presidential campaign, including:

1. Build a U.S.-Mexico border wall to prevent illegal immigrants from entering the United States;

2. Cut taxes, lower corporate and personal income taxes, and encourage companies to return to the United States;

3. Cancel Obamacare and launch better and cheaper health insurance plans;

4 . Revitalize U.S. manufacturing and create more jobs;

5. Cancel trade agreements and renegotiate trade agreements that are more beneficial to the United States.

These promises became Trump’s political platform and attracted the support of some voters. After being elected, Trump has fulfilled these promises to a certain extent, such as signing a tax reform bill and launching a new health insurance plan. But there are also some promises that have not been fulfilled. For example, the Mexican border wall was promised to be built, but the cost of building the border wall was not paid. Trump is a rare president who can deliver on his promises.
