Donald Trump's job approval numbers have been upside-down since he was sworn into office, and he has been unable to improve them significantly. Part of this is because people just don't like him. A bigger part is that they don't trust him -- believing him to be dishonest and untrustworthy (as many polls have shown).
But perhaps the biggest reason is that most people just don't think Trump cares about them. They believe he cares only about himself (and some of his rich friends and family). Trump has tried to say he's making things better for everyone, but his actions and policies tell a different story.
