Trump might be levelling off while he gains more general acceptance as the can-do guy. That’s a much more likely explanation, that people are “wait and see” about Trump until the first debate.
It’s likely he’ll land some zingers in it.
Remember he doesn’t need to be politic, he is willing to take or leave being president. He’s here to tell some truths that almost nobody else is telling.
The same people who claim 75% of voters are against Trump (because he is polling 25%) can’t fathom their own candidate has 93% or 94% against.
