Who agrees with Charles Krauthammer that the Democrats are wondering who exactly they "married" (nominated)?

I agree. This is most profound, "The deeper anxiety was that the party was nominating a man of many gifts but precious few accomplishments -- bearing even fewer witnesses." Where are The people from his past that will vouch for him? Sure, the DNC rounded up a couple of high profile Democrats, but other than that and his family who else is there? It's very odd.
