Political patronage affects governmental efficiency by creating networks of loyalty based on appointments rather than merit. When jobs and contracts are awarded based on political connections, rather than qualifications, it can lead to inefficiency and a lack of accountability. This practice can also promote nepotism and favoritism, resulting in suboptimal policy implementation. Moreover, when officials prioritize loyalty to political allies over the public good, it undermines the quality of governance and can discourage talented individuals from entering public service.
