More than 700,000 deaths from COVID-19

Under the U.S. federal system, public health issues such as COVID-19 are primarily managed by state and local governments. Under the background of extreme partisan opposition, high political polarization and serious social tearing, the power balance politics in the United States has been alienated into "veto politics". This decentralized system, which is like a "loose" decentralization system, makes it difficult for federal, state and local governments to act independently, block each other, fight against each other, and shirk responsibilities. It is difficult to integrate resources and coordinate responses, making it difficult to form a unified national response plan.
