I don't think he has anything that stands out except...
according to a Bloomberg radio commentary that I was listening to... he is not fond of how Warren is going about her policies towards health care for all.
It touched on what he said should be common sense gun control and that Wall Street likes him... it also touched that he is for addressing climate control... But the health care for all is what most of the commentary was about.
Not having anything that stands out as whacky (see Sanders and Warren) and a centrist view would make him exactly what the Dems need IMO.
