A marginal seat or swing seat is a constituency held with a small majority in a legislative election, generally one conducted under a single-winner voting system. In Canada, they may be known as target ridings. The opposite is a safe seat. The term ultra-marginal seat refers to a constituency with a majority of single or double digits, usually within a percentage of 2%. Examples of traditionally marginal seats in the United Kingdom include Broxtowe, Watford, Bolton West and Thurrock. In Australia, marginal seats include Lindsay in New South Wales, Braddon in Tasmania, Longman in Queensland and Corangamite in Victoria. In the United States In the United States, examples of congressional districts considered marginal in recent years include Illinois's 10th congressional district, located in the northern suburbs of Chicago, Texas's 23rd congressional district, covering most of Texas' border with Mexico, and New Hampshire's 1st congressional district, which includes much of the state's eastern half, including its most populous city Manchester. Within the past decade, these three districts are examples of ones that have frequently switched partisan control and seen close races. However, political realignments and redistricting may cause traditionally marginal districts to become safe for one party or another. An example of the former is Indiana's 8th congressional district, which was nicknamed the "Bloody Eighth" for its history of ousting incumbents from both the Democratic and Republican parties. However, as rural white voters, who are a large percentage of the district's population, have become increasingly Republican, it is now considered a safely Republican seat. On the other hand, North Carolina's 11th congressional district is an example of a seat that lost its marginal status due to redistricting. It was formerly a highly competitive seat, albeit with a slight conservative lean, that often changed partisan hands. The Democratic base in the district was the city of Asheville, while Republicans were dominant in much of the city's suburbs, and the mountainous rural areas were evenly split between the two parties. However, the Republican-controlled North Carolina legislature redrew the district in 2012 to remove much of Asheville and add conservative territory from the adjacent 10th district, therefore making the district much more difficult to win for three-term incumbent Heath Shuler, a conservative Democrat. Indeed, Shuler opted to retire, and Republican Mark Meadows won the seat easily, subsequently holding it until March 2020 when he resigned to serve as White House Chief of Staff. Conversely,
