Kansas Gov. Kathleen Sebelius accused Republicans on Tuesday of injecting race into the presidential campaign, arguing that they are using “code language” to convince Midwesterners that Democrat Barack Obama is different from them. “Have any of you noticed that Barack Obama is part African-American?” Sebelius asked with sarcasm. “(Republicans) are not going to go lightly into the darkness.” Sebelius was responding to a question from the audience at the Iowa City Public Library about the tenacity of Democrats and whether they would fight for victory as hard as Republicans in the closing weeks of the election. She did not elaborate on her comment.
