Charles O’Byrne had some pointed advice for his former boss David Paterson during their Feb. 21 meeting. Off with their heads. According to a well-placed source, Mr. O’Byrne, the former chief of staff and powerful consigliere who left the governor’s office under the cloud of a tax scandal, told Mr. Paterson to act quickly and decisively after the disastrous Senate selection process, get rid of some advisers and institute a wholesale change in staff. Despite some initial departures in the past few days–a communications director, a fund-raiser and, on the evening of Feb. 24, the consulting firm Global Strategy Group–the wholesale housecleaning hasn’t happened yet.
