Does the incumbent usually win reelection because they are better known?

Incumbents often have an advantage in reelection due to their established name recognition, which can lead to increased voter trust and familiarity. They typically have more access to campaign resources, established donor networks, and a record of experience in office. However, this advantage can be mitigated by factors such as public dissatisfaction with their performance or significant opposition challengers. Ultimately, while name recognition plays a key role, it is not the sole determinant of reelection success.
