There is no doubt that the yells were used for intimidation purposes where I work. These past four years have been basically hell in that regard. Hopefully things will smooth out after Obama leaves office. I don’t see the Blacks that I know as people who would get out and riot, many of them are very angry about the gay marriage thing and seem to be apathetic about Obama this time.
The overwhelming lack of enthusiasm for Obama reported in this thread makes riots seem unlikely.
