Well, it looks like Democrats in a Southern state have embarrassed party officials once again. Back in 2010, it was Alvin Greene in South Carolina, whose victory in that state's U.S. Senate primary so infuriated Palmetto State Congressman James Clyburn that he accused Greene of being a plant and called for a federal probe. Greene refused to step aside; incumbent Republican Jim DeMint defeated Greene in a landslide.
A similar script is playing out in Tennessee, where relative unknown Mark Clayton defeated seven other challengers in the Volunteer State's Democratic U.S. Senate primary. It turns out that Clayton is vice president of an alleged "hate group." If that characterization really fits Clayton's Public Advocate of the United States (there's ample reason to doubt that), then Associated Press reporter Lucas L. Johnson II "somehow" forgot to notice that a couple of national Democrats apparently agree with the group's supposedly "hateful" positions -- as well as, it would appear, President Barack Obama himself.
