The Commercial Appeal investigated the burning question of why four local mayors (Bartlett, Arlington, Collierville and Germantown) backed Tom Leatherwood in his quest to unseat the very popular and firmly entrenched Marsha Blackburn for Tennessee’s seventh Congressional District.

The CA has determined that these local leaders chose Leatherwood because they have an "uneasy relationship" with Blackburn. This probably due to the fact that the 7th Congressional District is the most gerrymandered in Tennessee, twisting it’s way across parts of 15 counties from Mississippi to Kentucky. So it is tough for Blackburn to maintain a close relationship with voters and elected officials across her entire district.

But the real story is that Blackburn, the popular incumbent, raised record amounts of campaign cash and outspent Leatherwood nearly 10 to 1 just to win by a 3 to 1 margin.

The result is that Leatherwood has positioned himself nicely to take Blackburn’s spot when she steps down to run for governor. And he’s warned her that she had better clean up her act before she does so.

Wins all around . . . eventually.
