If you are like most Americans, you have a strong opinion on how President Trump is doing his job. The July Post-ABC poll found that nearly three-quarters of Americans had a strong view of Trump’s performance — about a quarter strongly felt he was doing well and about half strongly felt that he wasn’t.

A new survey from Monmouth University layers another interesting detail on top of those numbers: Most of those opinions of Trump probably won’t change.

Overall, Monmouth found that Trump is doing a bit better on his approval rating than did other recent polls (including Gallup’s, where Trump hit a new low this week). About 4-in-10 Americans approve of Trump’s job performance; about half disapprove.

But Monmouth asked a follow-up question of those who had an opinion on how Trump was doing: Could he do anything to change your mind? (The specific wording for those who approved was “Can you think of anything that Trump could do, or fail to do, in his term as president that would make you disapprove of the job he is doing, or not?” For those who disapproved it was similar, with the addition of “other than resign.”)

About 6-in-10 of each group said that their minds were made up.

What does that mean? It means that a quarter of the population approves of the job that Trump is doing and won’t change their minds — and another quarter disapproves and says the same thing.

Or, put another way: More than half of the country has made up its mind on Trump and nothing he can do or say will dissuade them.

It’s important to note that this is just what people say they will do in the future, a bit of self-reporting that is worth taking with a grain of salt. We can also look at this as a sort of thermometer for how fervently people feel about the president, a sort of proxy for strong or more tepid approval or disapproval of how Trump is doing.

But it’s also eminently believable. If you’re one of the three-quarters of Americans who feels strongly about how Trump is doing, do you envision a scenario in which that changes?
