A final vote in the South Carolina State Senate is set for today over removing the Confederate flag from the State House dome. Yesterday, the Senate overwhelmingly approved a compromise bill to take the flag down. If given the OK today, the bill then goes to the Republican-controlled House, where leaders have already offered their own compromise plan. South Carolina is the only state that flies the Confederate flag above its State House. The NAACP is leading a tourism boycott of South Carolina until the flag is removed. Yesterday, tennis player Serena Williams, who is African American, withdrew from the Family Circle Cup next week in Hilton Head Island. She’s the biggest sports name to back the boycott.
