Excerpt:
An argument over who is more opposed to the Islamic faith and the construction of a mosque near Nashville has become an unlikely issue in a nasty Tennessee Republican congressional primary to be decided on Thursday.
Freshman Republican Representative Diane Black is challenged by Lou Ann Zelenik, who lost to Black in a primary to represent the rural district two years ago by less than 300 votes.
The heart of the struggle is over the Islamic Center of Murfreesboro, about 30 miles south of Nashville, which has been controversial since construction began two years ago.
