The previous mayor of Tulsa about jumped through her own rectum disavowing any allegiance with Bloomberg when a big list of his mayors cam out. Local opinion was that she just didn't like it being public info.
I believe you cracked a code.
I have a feeling that a lot of the mayors on this list aren't going to be very happy when their gun-toting constituents discover their elected chief of state is dancing with the dark side.
As I noted in that column Sam linked, some of these folks live in communities where rifles in gun racks is a pretty common sight.
