Dems Refuse to Kick Racist, Holocaust Denying AG Candidate off the Ballot.

Larry Darby, whose past exploits can be read here, here, and here, will be on the June 6 Democratic primary ballot. Darby is the founder of the Athiest Law Center whom believes blacks and whites should attend separate schools. Darby recently gave a speech to "pro-white" group in New Jersy. Here is what New Jersey's Democratic committee said about Darby; denying the Holocaust was "historical blasphemy."
"Hate and prejudice are destructive qualities that are not welcome in New Jersey and should be condemned wherever they occur," said party Chairman Joe Cryan. "Mr. Darby should turn around before crossing the Jersey stateline and then give thought to turning his abhorrent attitudes around as well."
In contrast, Alabama's Democratic Party Chair Joe Turnham says he was made aware of Darby's extreme views two weeks ago. I believe this statement to be flat-out untrue. I can myself find several instances (March 30 , Dec. 12, Fall 2005 Southern Poverty Law Center Report) before the 1st of May where Darby's extremist views were made known.
Exactly what are the requirements to run for office on the Democratic ticket? A pulse. Why does the Democratic Party allow this man to run. The New Jersey Democrats can't be too happy about a racist Alabama Democratic candidate attracting bad PR in their state. In fact, his candidacy embarrasses all citizens of Alabama. Darby is only bringing in around 12% of the primary vote so he is going to lose. What exactly is the upside of having him on the ticket?
So is Mr.Turnham telling the truth about when he first learned of Darby's views or is he just trying to save face?
