It's hard to say as conflicting reports float around out there. Some things claim his approval rating is increasing, and others say it is decreasing. And of course there's plenty of stories out there about people who "regret their vote" or whatever, but you can also find stories about upset people who then say they'd still vote for him.

I can't find it now but I did see something the other day where a question like "Are you happy with the job Trump is doing" had an overall positive response. BUT, asking "Are you happy with topic X" for a variety of X like economy, DOGE, etc and most of them were quite negative. I suspect this is closer to reality: people aren't happy but they're not blaming him.
