Rumor has it that the Fletcher campaign has cut a deal with Tony Young: deliver your voters for Nathan and in return Nathan's people will make it easier for Tony's transition to Sacramento or the County Board of Supervisors.
This is not as out there as it appears. Republicans have had a wire into the 4th City Council district for some time now delivering the votes that elected Horton to the Assembly and Roberts to the Board of Supervisors.
With term limits looming Tony needs somewhere to go. He has cast himself as the "reliable middle" of the debates at City Hall ensuring that he will not propose or initiate but will discuss and mediate. This keeps him out of anything controversial and makes him approachable to Republicans. Access to Republican donors and a D behind his name make him an attractive candidate for higher office.
