why do people think Donald Trump is bad to be a president?

Government isn't a business and he wants to run our country like it's a business but only as a dictator ignoring the Constitution and Congress.

He is so confusing.

Trump is a con man, and here is the evidence:

His childish and arrogant nature are why I don't support him. Plus too many of his plans line up with tax and spend liberal ones.

He is unpredictable, he talks just like Hitler, talks bad of other countries, making the U.S. in bad diplomatic relations.

Yes, and a bad person
