> when the majority of people who decided to vote voted for the person You're not wrong. However the portrayal of a mandate is a bit of a media fiction. He didn't have notably more votes than any other recent president.
But the people who did vote for him explicitly voted for all the stuff he's doing right now. Nothing that he's currently doing is surprising , except maybe for the fact that a politician actually followed through on so many campaign promises.
It's a far stretch to say that this is what the majority of his voters wanted. Certainly many Republican voters have seemed very upset about this stupid blitzkrieg dismantling of core services.
