“run as a social liberal and fiscal conservative with signature issues such as environmentalism and gun control.”
It would be very difficult to imagine Bloomberg running as a fiscal conservative! This is just not going to be allowed by the Left. Bloomie would split the liberal vote with Hillary and that is exactly why the Dems will not allow it.
But who is going to be tapped to put the bloody horse's head in Mike's bed? Having a sitdown with a sitting Mayor who happens to also be a multi-billionaire for the purpose of reading him the riot act is not something that I would necessarily volunteer for.
