He did not even win the popular vote, but if you are the president of the most powerful country in the world you can do whatever you want like call anyone you want a liar, shutdown the government because you want a stupid wall that not will bring anything useful at all, broke nuclear weapons pacts like we broke a deal for a candy with a boy, and nothings happens.
