Why did the Founding Fathers include the Commerce Clause as a power granted to Congress in the new United States Constitution?\

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

The Founding Fathers included the Commerce Clause as a power granted to Congress in the new United States Constitution because the founders of America wanted the federal government, specifically the Congress, to regulate trade in the United States and foreign trade too.

By granting the US Congress the regulation of interstate trade, they wanted to eliminate protectionist regulations on trade. The problem in modern US politics and economics is that the Commerce Clause has an extensive regulatory reach that not all the times has represented the most beneficial things for the US economy and the industry.
