The real test is what these folks do after the fact. Often people are timid, concerned intimated in a group and so will not act or express an opinion. Some will have instantly reacted because they prejudged Romney. However when the emotions settle down they may well change their opinion recognizing that Romney had risked a lot to stand in front of them to share his ideas for a better America knowing they would react negatively and hoping they would set aside their biases and apply some logical thinking about what he had shared and how it would benefit them.
