Supreme Corp rules SC voter suppression just fine

This is blatant voter suppression. The Supreme Corp (SC) ruled that South Carolina voters using mail-in ballots must have a witness sign it. This requirement is their State law but a judge suspended it for the primary due to the pandemic. That it's even State law is an atrocious suppression tactic. Another judge again put the requirement on hold for the general election due to the pandemic, the 4th Circuit upheld that ruling but the SC reinstated it. 

This after 200,000 ballots have already been mailed and 18,000 returned. The Corp did note that ballots cast before the ruling must be received within two days or will be thrown out. And of course with the intentional Post Office delays in mail delivery, how many of those voters will just lose their Constitutional right to vote? It's plain as day that even the SC sides with taking away that right.
