Confusion has certainly led to a drop in Cain’s support.
Of course, the confusion in question is Cain’s own when it comes to discussing policy, so the part of his comments I disagree with involves Cain’s attempt to pin the confusion on other people.
But hey, this still is progress. At least Cain acknowledges that he is losing support, which means that he has some semblance of a connection with reality. Would that his supporters could say the same.
