@kiwipaulb keep in mind that Trump voters are not a monolithic group.
Polling after he was elected the first time showed that they were a coalition of some extremely different groups with often completely opposite preferences and reasons for casting those votes. So it gets complicated.
Don't forget that there are some who vote for him just because they want to watch the chaos, and others who vote for him BECAUSE he's not a good leader, so they are betting on his being ineffective.
In other words, are the voters that completely agree with you and see your comment as a selling point!
