Which Anonymous Council Members Want JSK Gone?

During his re-re-election campaign, Mayor Bloomberg said he planned to make room for new blood in his administration should he win a third term. It's no surprise that City Hall News named Janette Sadik-Khan as one department head some have targeted for replacement, but while City Council members are often all too eager to complain about the DOT commish and her runaway safety improvements, this particular story cites but one disgruntled, unnamed source:

"A lot of elected officials do not like her-Democrats and Republicans-and they have made that known to the mayor," said one Council member who is close to the administration, adding that it would cost nothing, politically, to cut Sadik-Khan loose. "She doesn't represent any sort of ethnic group or constituency that the mayor's trying to pander to."

We'd love to know who on the council considers their non-driving constituents unworthy of "pandering." But since this no-cost declaration was issued anonymously, any guesses?
