This was the best question put to McGinn on "The Conversation" today:

About our upcoming mayor's personal grooming. I don't know how to approach that tactfully but this city absolutely cannot have a mayor who is as slovenly looking. We don't want him to go around this country or anyplace else dressed and groomed the way he is. He must have a clean-shaven face and properly cut hair. Thank you. Goodbye.

I guess it's not really a question. It's a declaration. But my quick transcript doesn't do the call justice. Listen here. The call—and McGinn's politic response—comes at the 35:20 mark.
