Incumbency

The role of incumbency 

Voting behaviour,turnout and gerrymandering 

Being a current elected official running for re-election significantly boosts one's prospects. In the 2018 midterms, 90.5% of incumbent Senate and House members who sought re-election emerged victorious. Similarly, in 2020, many incumbents easily won re-election, often by wider margins than their party's presidential candidate. For instance, in Maine, despite Trump losing to Biden in the statewide poll, long-standing Republican senator Susan Collins secured re-election effortlessly. Incumbents enjoy several key advantages. They tend to have higher name recognition among voters and can highlight past accomplishments, such as securing federal funding and jobs for their state or district. Many also serve on influential congressional committees that shape policies relevant to their region. Furthermore, they can emphasize their experience and dedication to public service. Additionally, they benefit from an established campaign infrastructure and support from donors, often amassing substantial campaign funds to deter potential challengers. However, being an incumbent does not guarantee job security. In the 2018 midterms, several incumbent Democrats, like Joe Donnelly of Indiana, and one Republican, Dean Heller of Nevada, lost their re-election bids. These losses were partly due to perceived vulnerability of their seats, leading to substantial external funding pouring into their opponents' campaigns. The highly contested Senate race in Florida, resulting in the ousting of incumbent Democrat Bill Nelson, witnessed a total campaign expenditure of approximately $118 million. At the presidential level, incumbency also provides an advantage. Since 1945, very few presidents have served only one term. Carter (1976–80) and Trump (2016–20) are the notable exceptions, as other one-term presidents, such as George H. W. Bush (1988–92), succeeded a two-term president from the same party. Additionally, most presidents secure more votes and Electoral College votes during their second term. Obama's reelection in 2012 stood out as an anomaly, winning by a narrower margin compared to his initial term.

·    Pork-barrel legislation This is when a member of Congress proposes an amendment to legislation that will bring benefits (especially financial ones, such as infrastructure projects or service provision) to a particular group. An amendment added by a politician to add expenditure to a bill that benefits their constituency is referred to as an 'earmark, which is often criticised for promoting unnecessary spending and contributing to the budget deficit. Even fiscal conservatives will engage in such proposals to improve their re-election chances. Some see pork-barrelling as evidence of the highly representative nature of Congress; others see it as a form of over-representation, in which financial benefits are not spread evenly around the country or constituency. In 2010 Republican leaders placed a moratorium on earmarks in order to restrict pork-barrel legislation, but this did not stop the practice altogether. In 2016, Congress passed legislation to spend $475 million on a new navy ship that the Defense Secretary and navy did not want, especially after a Pentagon report showing its unreliability. The project was supported by Representatives Byrne from Alaska and Ribble of Wisconsin, who represent districts with major shipbuilding companies.

·    Financial advantage Incumbents can attract more money than challengers, allowing them to run more successful campaigns. Challengers can struggle to gain name recognition and often find themselves under attack through well-funded negative adverts.

High incumbency re-election rates can be seen as a threat to US democracy, suggesting an ineffective level of representation. Some states tried to resolve this by creating term limits for their Congressmen and Senators, but this was struck down by the Supreme Court. Term limits would end the stagnation of politicians in Congress, but they would only be attacking a symptom of incumbency. The major underlying causes, such as funding and gerrymandering, would remain, along with significant concerns about how representative members of Congress were.
