Chris Christie is literally the biggest establishment/RINO there is. How about you crazy Trumpbot cultists demand your Fuhrer to disavow his endorsement?
Sit down
Christie is a not a member of the Washington cartel, Linda Graham is. No comparison at in the two politicians. Christie was also a hell of a US Attorney and put away many high level terrorists. Another endorsement Trump has gotten is Rudy Giuliani, another great former US Attorney, who was also Assistant Attorney General for Ronald Reagan.
You can bet that either Giuliani or Christie will be the the Attorney General if Trump is elected president. I can’t think of one accomplishment of Linda Graham except getting elected.
