AG Sessions is doing nothing of importance and cannot be replaced. Flight from the Blue Wall is turning the Red Edge Blue, the reverse is much slower due to state and local civil services becoming ever more left wing as a condition of employment. If the Blue Wall meltdown hits after the primaries but before the general election then this will work for Trump. After the election does no good. Before the primaries moderate Ds will be running in the general election which is problematical because most of the Blue state politicians have been robbing their states blind. That Sessions will prosecute but that will come across as a witch hunt. Dossiergate may get more publicity but without a special counsel prosecuting the deep state that will do nothing to turn the election.
