As others have already pointed out, this is a really poorly-formulated question. On any policy issues where he takes a position I agree with, I want him to be successful; on the rest I want him to fail. Has nothing to do with Trump the man, that's basically the position I'd take regarding any President.
But maybe more to your point, I have a strong distaste for Trump the man. I think he's a terrible person and I don't like the way he conducts himself, don't think he represents us in a positive light, etc. So in a more general sense (i.e. if I was ambivalent about policy issues), I want him to fail because I don't want to live in a society that believes a man like Trump is qualified to be our President. I want to raise my boys to be the opposite of Donald Trump, and that will be easier to do in a universe where he's a massive failure as a President.
