Thompson's recent comments on the Confederate flag drew protests Wednesday.
Clad in jackets bearing the stars-and-bars and holding signs reading "South Carolina hates Fred Thompson" and "Fred Thompson go home," the protesters said Thompson was not a "true southerner."
Jim Hanks, chairman of the South Carolina League of the South, said Thompson that Thompson's answer was worse than Romney's because Thompson is from a southern state.
Asked about the flag during last week's debate, Thompson said that, "as far as a public place is concerned, I am glad that people have made the decision not to display it as a prominent flag, symbolic of something, at a state capital."
But the former Senator from Tennessee qualified his statement: "As a part of a group of flags or something of that nature, you know, honoring various service people at different times in different parts of the country, I think that's different."
