If they already are disposed not to vote for Trump, not many of them will change their minds. However, you might ask, why would any of them at all change their minds?
First of all, of those people not inclined to vote for Trump some of them would not vote for him ever, ever, ever. Others have varying degrees of dislike. Of those, some of them only have a minor dislike. If their dislike of the Democrats could be increased a bit, it might exceed their dislike for Trump.
I think that when the Democrats lay out Trump's crimes, an awful lot of people will say, "Huh? Those aren't crimes." They'll be upset at the anti-Trump forces who wasted their time.
