CHATTANOOGA (WRCB)-  Hamilton County School Board member David Testerman plans to run for the District 10 State Senate seat being vacated by Sen. Andy Berke.  Testerman will run in the Democratic primary in August.

Testerman, who represents District 8 (East Ridge, Brainerd areas) on the School Board, told Eyewitness News, "It will be an uphill fight, but I don't mind a good fight."

The 10th District, predominantly Democratic for many years, has been redrawn for the 2012 election, with the balance of voters shifting in favor of the Republican party.  Testerman is the only Democrat who has picked up papers for the seat so far.  Greg Vital and Todd Gardenhire have announced their intentions to seek the seat under the Republican banner.  The winner of each party's primary will face each other in the November general election.  

Berke has not announced his plans, although he is said to be considering a run for Chattanooga mayor in 2013.  State Representative Vince Dean, a Republican who represents the East Ridge area in the State House, had earlier considered a race for Berke's seat, but has since indicated he will run for re-election to his House seat.

Testerman was elected to the School Board in 2010 after retiring from the School District a few years earlier.  He had served as a teacher and principal in schools including Ganns Middle Valley, Bachman, Westview, White Oak, Sale Creek and East Ridge High. 

He says he plans to remain on the School Board during his State Senate campaign, and is checking with state officials to see if he could serve in both capacities at once, if he is elected to the Senate.
