Here’s a take from me. In a 650-word column, its hard to do a lot of nuance. So here’s a dose of nuance: He’s untested, and it’s not clear he can take a punch yet. (In contrast, it’s clear that Hillary can. One experienced Dem operative I was talking to yesterday described her as the toughest politician he has ever known.) He still has to put substance on his bones. He has no national-security experience. And the media enthusiasm for him could fade.
