Final answer:
Incumbency advantage is largely aided by an incumbent's name recognition and their capacity to offer constituent services, both of which play critical roles in securing reelections.
Explanation:
Two key factors that contribute to incumbency advantage are name recognition and the ability to provide constituent services.
An incumbent's name recognition comes from their established presence in the political landscape, often highlighted by media coverage and previous campaign efforts. Voters are more likely to choose familiar names, which benefits incumbents during elections.
Additionally, incumbents have the power of office resources to assist constituents, which can turn into electoral support as they are seen as helpful and effective in addressing local issues.
