Candidates in a Tennessee Republican congressional primary are engaged in an epic battle to determine who's more of a wretched bigot. Lou Ann Zelenik, who lost to current congresswoman Diane Black two years ago, promises to be super racist and awful towards Muslims like the ones who wanted to build a mosque in Murfreesboro, Tennessee a couple of years ago.

"I will work to stop the Islamization of our society, and do everything possible to prevent Sharia law from circumventing our laws and our Constitution," Zelenik said.

Black, for her part, also insists she's a lowest-common-denominator-pandering fear mongerer, but just one who has a more nuanced grasp of the constitution (nuanced in the sense that she probably skimmed it once or twice in the background of ad she read while buying gold).

"No one is more opposed to Sharia law, radical Islam and terrorism than Diane Black, but unlike her opponent, Diane Black respects our Constitution," her campaign spokeswoman Jennifer Coxe-Baker said.
