Rob Ford was a flawed human. But a certain segment of Toronto connected with him. Rob won because of a confluence of factors and he won a majority to become mayor of Toronto. I actually cheered for Rob until all the personal stuff incriminating him was disclosed. Rebounded up being a terrible mayor, a role for which he was never suited.
His brother Doug however, carries this torch for his brother that frankly will never work. Doug too is flawed but in a manipulative , bullying manner. Doug wants to be the far right voice of the Conservative movement in the GTA but, that ship has sailed. Doug has a meaness and rough edge that makes his personality toxic. 
We've had enough of Harper, anything Doug Ford endorses is hollow and irrelavent.
