Racist southern politicians use “law and order” as a form of segregation because they do not have the option to be openly racist or they will face backlash from the north and it is no longer acceptable to allow blatant division of people with different skin, so they came up with law and order to make segregation like a form of justice. “Law and order” gives them special advantages because it allows racist police officers to do stop and frisk or beat a person of color. It even allows police officers to wrongly put black people in prison segregating them from white people.
I believe that southern strategies is still affecting politics because some politicians believe that black and white people should be segregated and by appealing to them you can get their support. For example in the excerpt it states “Nixon reportedly remarked with glee that the ad “hits it right on the nose. It’s all about those damn Negro–Puerto Rican groups out there.” This shows by building a wall between the races he was able to get most of the south’s support in his election.
