Who would have been happier with their representation in the house, small states or big states? why?

Big states because representation in the house is based on population. The more people a state has, the more representatives there will be.

I believe you are talking about when the US was discussing whether they should have equal representation in the legislative house or unequal representation based on population density. The small states would have been happy with equal representation because that would mean their state interests would not be overruled by larger state populations, such as Virginia (back then, Virginia had a lot of people : P). Larger states would have been more happy with unequal representation based on population density because they thought it was unfair to have smaller states be equally represented when they have more people being represented in the house. IN the end, the compromise was the House of Representatives and the Senate in the legislative branch of the government. The HoR had unequal representation based on population density and the Senate had equal representation from each state.
