I think Carter still lives in Georgia and I am sad to say that there is still a lot of racism here. Remember, until 50 years ago this state was still officially segregated. Twenty years ago I saw someone in a KKK robe handing out literature. (But the local PD sent a large Black officer to talk to him and I haven't ever seen the guy in the hood again.) So his statements may be influenced by comments he is hearing. But he is wrong--there are plenty of people opposed to Obama for reasons other than race.
