Rep. Diane Black isn't exactly an ideal target for the Democratic Party. Her district, per Cook Political Report, has a PVI of R+21 and she first elected 2010 with 69.6% of the votes, taking over Rep. Bart Gordon who chose not to run for re-election in 2010. In 2012, Black won re-election by an even wider margin by 76.4% and didn't face a single Democratic challenger. Therefore, the odds aren't in the Democratic Party's favor at this point.
However, as covered our previous diaries via our group, Knowledge Democrats, TN-06 Democratic Candidate Amos Powers is still continuing on and being active on the campaign trail.
For any of you who live in TN-06 or nearby, on April 12th, Amos Powers will be appearing at a Democratic Candidate forum at Manchester, TN. Full details of the event below:
Democratic Candidate ForumWHEN: April 12, 2014 at 5pm - 8pm
