Polling Ray Kelly?

A reader just called in with an interesting tip about Ray Kelly-related polling.

Apparently, a little before 9:00 last night, a registered Democrat who votes in every election got a call from a pollster asking about hypothetical mayoral match-ups between (hypothetical!) Republican candidate Kelly and each of the likely Democratic candidates. The caller also asked, according to the source, what the current mayor is “lacking.”

Does anyone know anything else about this? Polling Ray Kelly?
