The stipulation about commerce regulation won strongest support from big cities and centers of manufacturing industry and commerce, such as New York, Philadelphia and Boston, because they knew that the regulation of the central government would be quite helpful for the sale of their products. Alexander Hamilton, one of the most active representatives in the Constitutional Convention, pointed out that free trade in the whole nation was very profitable for any kind of business. For example, when the local market was weakened, the markets in other states and areas of the country would support the sale of the producers, thus their business could keep developing.
