Historically, this U.S. region voted solidly Democratic but is now strongly Republican; Bush carried every Southern state in 2000.

• A. Solid North
• B. Swing region
• C. Solid South
• D. Rust belt

Answer: (C)

The region is described by a long-standing party realignment: it used to vote consistently for the Democratic Party in presidential elections, but over the later 20th century shifted to strongly supporting the Republican Party. This shift culminated in Bush carrying every Southern state in 2000, illustrating a durable change in voting patterns rather than a temporary fluctuation. The label Solid South precisely captures that history—a region once a Democratic stronghold that became a reliable Republican bloc in national contests. Other regional names don’t fit: Solid North isn’t a standard way to describe this pattern, the Rust Belt refers to the industrial Midwest and Northeast, and a swing region suggests volatility rather than this enduring realignment.
