NASHVILLE - Republican state Sen. Jim Tracy's first major fundraiser for his 4th Congressional District bid is set for March 14 in Murfreesboro, Tenn.

Former Gov. Winfield Dunn; Lt. Gov. Ron Ramsey; Senate Speaker Pro Tempore Bo Watson, R-Hixson; and Rep. Ron Travis, R-Dayton, are among the honorary hosts.

The per-person price of a ticket is $250 while tickets for members of the sponsor committee are $2,500 per person or couple and $1,000 for host committee members.

Dr. Warren McPherson and his wife, Beverly, are holding the event in their home.

Tracy, of Shelbyville, is running against U.S. Rep. Scott DesJarlais, R-Tenn., a physician whose past personal controversies have made him vulnerable to challenge, Republicans say. State Rep. Joe Carr, R-Lacassas, also is weighing a bid, but Tracy has been the first challenger to announce officially.
