2. what are some major demographical differences that exist between the senate and house of representatives in the 108th congress?

In the House of Representatives, the election is made proportionally to the number of inhabitants living in each state. In this way, more populous states, like California, elect more representatives than states less populous like Hawaii.

In the Senate, the election is majority and two representatives are elected by each state. In this way, the interests of the states will be represented and defended on equal terms.

In this way, the 108th congress of the United States was represented by 100 senators and 435 deputies, respecting the demographic and proportional characteristics of the USA.
