Editor's Note: In the final 100 days before Election Day, CNN has been profiling one race at random each day from among the nation's top 100 House races, which we've dubbed "The CNN 100." Read the full list here . Today's featured district is:
Tennessee's 6th: Diane Black (R) v. Brett Carter (D)
Primary: August 5, 2010
Location: Middle Tennessee
Days until Election Day: 63
(CNN) – Of all the House Democrats who are retiring ahead of the 2010 midterm elections, Democratic Rep. Bart Gordon's decision to exit the stage may have stung the most.
After all, Gordon, who's served in Congress for 25 years, hails from a decidedly conservative swath of Tennessee that in 2008 voted for John McCain over President Obama by a 62-37 percent margin. The district, encompassing Middle Tennessee and parts of the Appalachian Mountain chain, has traditionally been the scene of sprawling farmlands and endless countrysides.
But an economic boom earlier this decade transformed the landscape somewhat when several corporations established shop in the district to avoid higher taxes in nearby Nashville. The result has been one of the fastest growing districts in Tennessee, bringing in scores of new voters who largely tilt Republican despite Democrats' best efforts to remove the district's most conservative corners during redistricting in 2002.
The Republican candidate is Diane Black, a state senator who narrowly won the nomination over a handful of other GOP candidates in a primary earlier this month. Black holds the conservative line on most positions, favoring a repeal of the Democratic health care legislation and an extension of the tax cuts passed under President George W. Bush.
The Democratic candidate is Brett Carter, a veteran of the Iraq war but a political unknown. Carter is running on a moderate platform, saying the health care legislation "must be improved" and calling for an investigation into President Obama's Environmental Protection Agency after the BP oil spill.
But while Carter's stances have a chance at appealing to the district's conservative voting bloc, he is at a money disadvantage to Black and will likely have trouble getting his name out. At last check, Black has spent more than six times what Carter has and also enjoys a war chest that is twice the size of Carter's, $196,678 to $99,929.
When you add to that the Democratic Congressional Campaign Committee's reticence to spend any money of their own on this race, it's more than likely this district will go from blue to red.
