In the latest sign of rising opposition to the Confederate flag, the Daytona International Speedway has announced it will conduct a flag exchange this weekend, offering NASCAR fans the chance to swap out their Confederate flags for U.S. flags. NASCAR bans the Confederate flag from official materials and race cars, but has not blocked fans from raising it over campsites and motor homes in the infield of racetracks. Many have criticized NASCAR for not simply banning the flag altogether.
