I doubt you're going to get very many unbiased answers to this question. Predictably, Republicans will think he'll be a disaster and Democrats will think (mostly) that he'll do an excellent job.
I actually don't think he'll necessarily be a disaster. I have warned my fellow Republicans countless times not to think that he'll definitely be incredibly unpopular and that we'll be embraced. Far too many on my side are way too confident about that happening.
That being said, yes, I think he'll be bad. I'm just not going to act like I know this for a fact.
