Question

Quizplus · Accepted Answer

Money is a deterrent to congressional political challengers because it signals that the incumbent knows how to raise money and will run a strong campaign. Incumbents who can raise a lot of money can use it to fund their campaign and run a positive or negative campaign, making it difficult for challengers to compete. Additionally, donors may be more willing to give money to an incumbent who is perceived as successful and likely to win, further boosting the incumbent's advantage.
