full_context: Document 1: Tennessee: By 1960 African Americans comprised 16.45% of the state's population. It was not until after the mid-1960s and passage of the Voting Rights Act of 1965 that they were able to vote in full again, but new devices, such as at-large commission city governments, had been adopted in several jurisdictions to limit their political participation. Former Gov. Winfield Dunn and former U.S. Sen. Bill Brock wins in 1970 helped make the Republican Party competitive among whites for the statewide victory. Tennessee has selected governors from different parties since 1970. Increasingly the Republican Party has become the party of white conservatives.
Document 2: Tennessee: In the 2000 presidential election, Vice President Al Gore, a former Democratic U.S. Senator from Tennessee, failed to carry his home state, an unusual occurrence but indicative of strengthening Republican support.

Johnson, Jimmy Carter, Bill Clinton) usually fare better than their Northern counterparts do in Tennessee, especially among split-ticket voters outside the metropolitan areas.

Document 13: Tennessee: In the early 21st century, Republican voters control most of the state, especially in the more rural and suburban areas outside of the cities; Democratic strength is mostly confined to the urban cores of the four major cities, and is particularly strong in the cities of Nashville and Memphis. The latter area includes a large African-American population. Historically, Republicans had their greatest strength in East Tennessee before the 1960s. Tennessee's 1st and 2nd congressional districts, based in the Tri-Cities and Knoxville, respectively, are among the few historically Republican districts in the South. Those districts' residents supported the Union over the Confederacy during the Civil War; they identified with the GOP after the war and have stayed with that party ever since. The 1st has been in Republican hands continuously since 1881, and Republicans (or their antecedents) have held it for all but four years since 1859. The 2nd has been held continuously by Republicans or their antecedents since 1859.
