Final answer:
The rise of candidate-centered campaigns has had a positive effect on improved policy representation.
Step-by-step explanation:
The rise of candidate-centered campaigns has had a positive effect on improved policy representation. In candidate-centered campaigns, candidates are self-reliant and less reliant on political parties. This allows them to focus on their own policy goals and connect directly with voters, which can lead to better representation of the issues and concerns of the people they aim to serve. For example, candidates who are independently wealthy or have a strong grassroots following can prioritize policies that align with the interests of their supporters, rather than following a party's platform.
