There is no household registration management system in the United States. What if someone repeatedly registers to vote in different places? From the work point of view, there is no way to completely prevent repeated registration or voting throughout the country. However, the laws dealing with this phenomenon are very strict. According to the law, if found out, they will be sentenced to prison.
The supervision of news media, especially the mutual supervision between candidates, is one of the most important factors for the strict and fair implementation of these laws throughout the country. The government and government officials remain neutral in the election organization. In order to ensure that the electoral institutions strictly enforce the law and realize fair elections, candidates will station supervisors in each constituency to supervise each other. In this American election, both sides organized a strong team of lawyers and sent them to some important places where election disputes may occur. Once the other party is found to have violated the law, they will immediately resort to the law.
