What do you expect? He's from a state with a ton of military bases, I can think of six of them off the top of my head without even looking it up. On top of that, South Carolina is easily the most racist state in the Union and Graham is right out of the Strom Thurmond mold.
South Carolina is perfect example of the failure of Reconstruction. Here's an example of the Black Codes--yeah, that's what they were called--enacted right after the Civil War:
South Carolina began to establish Black Codes immediately. The Constitution of 1865, passed only a few months after the Civil War ended, failed to grant African-Americans the right to vote. It also retained racial qualifications for the legislature. Consequently, black people had no power to combat the unfair laws. Some of the Black Codes that were passed around this time stated:
"No person of color shall migrate into and reside in this state, unless, within twenty days after his arrival within the same, he shall enter into a bond with two freeholders as sureties"
"Servants shall not be absent from the premises without the permission of the master"
Servants must assist their masters "in the defense of his own person, family, premises, or property"
No person of color could become an artisan, mechanic, or shopkeeper unless he obtained a license from the judge of the district court β a license that could cost $100 or more.
