In Tennessee. The guy had won the nomination. Here's his sin - he does some work for an advocacy group called Public Advocate (I never heard of them) that is pro-life and is against gay marriage.
Clayton defended his work for Public Advocate of the United States, the pro-life, pro-marriage group in question, and said he was disappointed with the Tennessee Democratic Party’s “zero-sum politics.”
“It’s not necessarily surprising, unfortunately,” he said in a phone interview. “But that’s not the way I deal with my political opponents. I have good friends who are liberals.”
I have friends who think they can work within the Democrat Party to change their anti-life positions. Right. Good luck with that.
