Which of these charming gents is Virginia governor Ralph Northam?

Gov. Ralph Northam (D)’s medical school yearbook page has a striking photo on it. 1984.
The page is labeled Ralph Shearer Northam, along with pictures of him in a jacket and tie, casual clothes and alongside his restored Corvette.
It shows two people, one in plaid pants, bow tie and black faced, and the other in full Klan robes. Both men appear to be holding beer cans.
The person in black face is smiling. Beneath the photo is a writeup about Northam listing his alma mater, noting that his interest is pediatrics and giving a quote: “There are more old drunks than old doctors in this world so I think I’ll have another beer.”
