The 7th congressional district of Tennessee is a congressional district located in parts of Middle and West Tennessee. It has been represented by Republican Mark E. Green since January 2019. Current boundaries The district is located in both West and Middle Tennessee. It stretches as far north as the Kentucky border, as far south as the Alabama border, as far east as Franklin, and as far west as Camden. It is currently composed of the following counties: Cheatham, Dickson, Decatur, Hickman, Houston, Humphreys, Montgomery, Perry, Robertson, Stewart, and Wayne. It also includes significant portions of Benton, Davidson, and Williamson. Characteristics The seventh district has significant suburban and rural areas. Although most of the area is rural, more than half of the district's vote is cast in either Montgomery County (Clarksville) or Williamson County (Franklin, Brentwood). By most measures, Williamson County is the wealthiest county in the state and is usually ranked near the top nationally. The district has a very strong military presence, as it includes Tennessee's share of Fort Campbell. Politically speaking, the area was secessionist and part of the Democrats' “Solid South” for a century after the Civil War, excluding the Unionist Highland Rim bloc of Henderson, McNairy, Hardin and Wayne Counties. However, since being carried by George Wallace in 1968 it has become and remained one of the most Republican areas in Tennessee, and has not been represented by a Democrat since the early 1970s. The presence of Nashville's suburbs gives it a character similar to those of most affluent suburban districts in much of the South until the mid-2000s. It has a strong social conservative bent; many of the state's most politically active churches are either located here or draw most of their congregations from here. The rural secessionist counties are similar demographically to the 8th district and returned to the Democrats until the 2000s; four of the five Tennessee counties won by George McGovern lie within this district. However, since the mid-2000s these counties have turned overwhelmingly Republican in all elections. The only area where Democrats currently compete on anything resembling an even basis is in Clarksville, which still occasionally elects Democrats to the state legislature.
